Vietnamese Pronunciation

Vietnamese pronunciation may seem difficult at first because the language uses many accent marks, but its spelling system is highly systematic. Once you understand the alphabet, vowels, consonants, and tones, written Vietnamese gives you strong clues about pronunciation.

The Vietnamese Alphabet

Vietnamese uses the Latin-based chữ Quốc ngữ (national language script). The alphabet contains 29 letters:
A Ă Â B C D Đ E Ê G H I K L M N O Ô Ơ P Q R S T U Ư V X Y
The letters f, j, w, and z are not part of the traditional Vietnamese alphabet, although they may appear in foreign names and modern terminology.
Several letters represent sounds that are different from what their appearance may suggest. In particular, d and đ are separate letters with different pronunciations.

Vietnamese Vowels

Vietnamese has a rich vowel system. The main vowel letters are:
a, ă, â, e, ê, i, o, ô, ơ, u, ư, y
Marks such as those in ă, â, ê, ô, ơ, and ư are part of the vowel itself. They are not tone marks.
Important contrasts include:

• a – ă – â

• e – ê

• o – ô – ơ

• u – ư
  Vietnamese also uses many vowel combinations, as in:
  hai (two)
  tôi (I; me)
  người (person)
  mười (ten)

Important Consonants

Some Vietnamese consonant combinations represent sounds that learners should practice carefully.
ng / ngh — as in người (person) and nghe (to listen)
nh — as in nhà (house; home)
ph — pronounced approximately like f, as in phở (Vietnamese noodle soup)
kh — a sound produced toward the back of the mouth, as in không (no; not)
th — an aspirated t, as in tháng (month)
Final consonants can also be very short and abrupt:
một (one)
học (to study; to learn)

The Six Vietnamese Tones

Tone is essential in Vietnamese because changing the tone can change the meaning of a word.
Northern Vietnamese traditionally distinguishes six tones:

ToneNameExampleNo written markngang (level)maGrave accenthuyền (falling)màAcute accentsắc (rising)máHookhỏi (dipping)mảTildengã (broken/rising)mãDot belownặng (heavy)mạA word without a visible tone mark still has a tone: the ngang tone.

Tone Marks and Vowel Marks

Vietnamese uses two different kinds of diacritics.
The marks in ă, â, ê, ô, ơ, and ư change the vowel sound.
Tone marks indicate how the syllable is pronounced.
For example:
a – á – à – ả – ã – ạ
all contain the same basic vowel but different tones.
By contrast:
a – ă – â
represent different vowels.

Regional Pronunciation

Vietnamese pronunciation varies between northern, central, and southern Vietnam.
Hanoi pronunciation is commonly used as a reference for Northern Vietnamese, while Ho Chi Minh City represents an important Southern variety. Differences can affect tones, vowels, and consonants, but the same standard writing system is used throughout Vietnam.
Beginners should ideally choose one major pronunciation model and use it consistently while learning.

Key Point

Vietnamese pronunciation becomes much easier once you stop seeing the accents as decoration. Every letter and mark carries useful information. Learn each new word together with its vowel sounds and tone, for example cảm ơn (thank you), xin chào (hello), and không (no; not), rather than learning the letters and tones separately.

Vietnamese Nouns

Vietnamese nouns are relatively simple because they do not change form according to grammatical gender, number, or case. A noun normally remains exactly the same whether it refers to one object or several, and its grammatical role is usually understood from word order and context.

No Grammatical Gender

Vietnamese nouns do not have masculine, feminine, or neuter gender. The same grammatical structures are therefore used with nouns referring to people, animals, objects, and abstract ideas.
For example:
người (person)
nhà (house)
sách (book)
tình yêu (love)
When it is necessary to indicate natural sex, additional words can be used, such as nam (male) and nữ (female).

Singular and Plural

Vietnamese nouns do not normally change their form to indicate plural meaning.
For example:
học sinh (student; students)
quyển sách (book)
những quyển sách (books)
Plural meaning can often be understood from context or expressed with words such as các (plural marker for a defined group) and những (plural marker).
các sinh viên (the students)
những người bạn (friends; some friends)
When a number is given, a separate plural ending is unnecessary.

Classifiers

One of the most important features of Vietnamese nouns is the use of classifiers. A classifier is a word placed between a number or certain determiners and the noun.
Common classifiers include:
cái (general classifier for many objects)
con (classifier for many animals and some living things)
người (classifier for people)
quyển (classifier for books and bound volumes)
For example:
một cái bàn (one table)
hai con mèo (two cats)
ba người bạn (three friends)
bốn quyển sách (four books)
The correct classifier depends on the type of noun and should often be learned together with it.

Nouns with Numbers

The usual pattern when counting nouns is:
number + classifier + noun
For example:
một chiếc xe (one vehicle)
hai cái ghế (two chairs)
ba con chó (three dogs)
The noun itself does not change after a number.

Demonstratives

Vietnamese demonstratives usually follow the noun rather than appearing before it.
Common forms include:
này (this)
đó (that)
kia (that over there)
For example:
ngôi nhà này (this house)
cuốn sách đó (that book)
người kia (that person over there)
If a classifier is used, the usual order is classifier + noun + demonstrative:
cái bàn này (this table)

Possession

Possession is commonly expressed with của (of; belonging to).
The basic structure is:
noun + của + possessor
For example:
nhà của tôi (my house)
xe của anh (his/your car, depending on context)
sách của giáo viên (the teacher's book)
In everyday Vietnamese, của can sometimes be omitted when the relationship is already clear.

Compound Nouns

Vietnamese frequently creates nouns by combining two or more words. Many everyday concepts are therefore written as separate syllables even though they function together as one lexical unit.
Examples include:
bệnh viện (hospital)
sân bay (airport)
nhà hàng (restaurant)
điện thoại (telephone)
máy tính (computer)
Because Vietnamese words are normally separated by spaces according to syllables, a single concept may visually resemble several independent words.

Key Point

Vietnamese nouns do not require learners to memorize gender, case endings, or regular plural forms. The main challenge is learning how nouns combine with classifiers, numbers, demonstratives, and possessive expressions. Instead of learning only sách (book), for example, it is useful to recognize natural combinations such as một quyển sách (one book), những quyển sách (books), and quyển sách này (this book).

Vietnamese Numbers

Vietnamese numbers and quantifiers are relatively simple because nouns do not normally change form after numbers. Instead, Vietnamese often uses classifiers between a number or quantity word and the noun. Quantifiers such as nhiều (many; much), ít (few; little), mỗi (each; every), and tất cả (all) help express quantity without changing the noun itself.

Basic Numbers

The basic Vietnamese numbers are:
một (one)
hai (two)
ba (three)
bốn (four)
năm (five)
sáu (six)
bảy (seven)
tám (eight)
chín (nine)
mười (ten)
Larger numbers are built systematically from these forms.
For example:
mười một (eleven)
mười hai (twelve)
hai mươi (twenty)
ba mươi (thirty)
một trăm (one hundred)
một nghìn (one thousand)

Numbers with Nouns

When counting nouns, Vietnamese commonly uses:
number + classifier + noun
For example:
một cái bàn (one table)
hai con mèo (two cats)
ba người bạn (three friends)
bốn quyển sách (four books)
The noun itself remains unchanged regardless of quantity.

Classifiers

Classifiers identify the type of noun being counted.
Common examples include:
cái (general classifier for many objects)
con (classifier for many animals)
người (classifier for people)
chiếc (classifier for vehicles and certain objects)
quyển (classifier for books)
For example:
hai chiếc xe (two vehicles)
ba con chó (three dogs)
năm người (five people)
The appropriate classifier often needs to be learned together with the noun.

Một

một means one and can also function similarly to a/an in some contexts.
For example:
một người bạn (a friend; one friend)
một ngôi nhà (a house; one house)
một câu hỏi (a question)
Vietnamese does not have articles equivalent to English a and the, so một sometimes supplies an indefinite meaning when the quantity one is relevant.

Numbers Above Ten

Vietnamese numbers are constructed regularly.
For example:
hai mươi ba (twenty-three)
bốn mươi sáu (forty-six)
một trăm hai mươi (one hundred and twenty)
Some number forms change slightly in compounds. một may become mốt after tens, năm may become lăm, and bốn may sometimes become tư.
Examples:
hai mươi mốt (twenty-one)
ba mươi lăm (thirty-five)
hai mươi tư (twenty-four)
These patterns are especially common in everyday counting.

Nhiều

nhiều means many or much.
For example:
nhiều người (many people)
nhiều sách (many books)
nhiều thời gian (much time)
In a sentence:
Có nhiều người ở đây. (There are many people here.)
Unlike exact numbers, nhiều does not always require a classifier.

Ít

ít means few or little.
For example:
ít người (few people)
ít tiền (little money)
ít thời gian (little time)
It can also be modified:
rất ít (very few; very little)
quá ít (too few; too little)

Một Ít

một ít means a little or a small amount.
For example:
một ít nước (a little water)
một ít thời gian (a little time)
Tôi biết một ít tiếng Việt. (I know a little Vietnamese.)
It is often used with substances, abstract nouns, and uncountable quantities.

Vài

vài means a few; several.
For example:
vài ngày (a few days)
vài người (a few people)
vài câu hỏi (a few questions)
It expresses a small, indefinite number rather than an exact quantity.

Một Vài

một vài also means a few; several and is slightly more explicit.
For example:
một vài cuốn sách (a few books)
một vài người bạn (a few friends)
Tôi có một vài câu hỏi. (I have a few questions.)

Mỗi

mỗi means each or every.
For example:
mỗi ngày (every day)
mỗi người (each person)
mỗi tuần (every week)
In a sentence:
Tôi học tiếng Việt mỗi ngày. (I study Vietnamese every day.)
Mỗi người có một vé. (Each person has one ticket.)

Mọi

mọi means every; all and is often used with general categories.
For example:
mọi người (everyone)
mọi ngày (every day)
mọi thứ (everything)
mọi nơi (everywhere)
A very common expression is:
Mọi người khỏe không? (Is everyone well?)

Tất Cả

tất cả means all; all of.
For example:
tất cả mọi người (everyone; all people)
tất cả học sinh (all students)
tất cả các sách (all the books)
It can also stand alone:
Tất cả đều đúng. (All of them are correct.)

Cả

cả can mean all; entire; both depending on context.
For example:
cả ngày (all day)
cả tuần (all week)
cả hai (both)
cả gia đình (the whole family)
In a sentence:
Tôi làm việc cả ngày. (I work all day.)

Cả Hai

cả hai means both.
For example:
Cả hai đều đúng. (Both are correct.)
Tôi thích cả hai. (I like both.)
It can be followed by a noun:
cả hai người (both people)

Một Số

một số means some; a number of.
For example:
một số người (some people)
một số vấn đề (some problems)
một số quốc gia (some countries)
It is common in neutral and formal writing when the exact number is not specified.

Mấy

mấy means how many or sometimes a few, depending on context.
In questions:
Bạn có mấy người con? (How many children do you have?)
Bạn ở đây mấy ngày? (How many days are you staying here?)
In some conversational contexts, it can refer to a small unspecified number.

Bao Nhiêu

bao nhiêu means how many or how much and can be used for both countable and uncountable quantities.
For example:
Cái này bao nhiêu tiền? (How much is this?)
Có bao nhiêu người? (How many people are there?)
Bạn cần bao nhiêu nước? (How much water do you need?)

Enough

đủ means enough; sufficient.
For example:
đủ tiền (enough money)
đủ thời gian (enough time)
đủ người (enough people)
In a sentence:
Tôi không có đủ thời gian. (I do not have enough time.)
Chúng ta có đủ thức ăn. (We have enough food.)

Too Much and Too Many

Vietnamese can express excessive quantity with quá nhiều (too much; too many).
For example:
quá nhiều người (too many people)
quá nhiều công việc (too much work)
Tôi uống quá nhiều cà phê. (I drink too much coffee.)
For insufficient quantity:
quá ít (too little; too few)

More

thêm can mean more; additional.
For example:
thêm một cái (one more)
thêm hai ngày (two more days)
Tôi cần thêm thời gian. (I need more time.)
It is extremely common when requesting an additional quantity.

Only

chỉ means only and can limit a quantity.
For example:
chỉ một người (only one person)
chỉ hai ngày (only two days)
Tôi chỉ có một câu hỏi. (I only have one question.)
The position of chỉ indicates what is being limited.

Approximately

Vietnamese can express approximate quantities with words such as khoảng (approximately; around).
For example:
khoảng mười người (about ten people)
khoảng hai giờ (about two hours)
Tôi ở đó khoảng một tuần. (I stayed there for about one week.)

More Than and Less Than

Quantities can be compared with hơn (more than) and ít hơn (less; fewer).
For example:
hơn mười người (more than ten people)
hơn một trăm năm (more than one hundred years)
ít hơn năm phút (less than five minutes)
These forms are common with measurements, ages, prices, and statistics.

Ordinal Numbers

Ordinal numbers are commonly formed with thứ followed by a number.
For example:
thứ nhất (first)
thứ hai (second)
thứ ba (third)
thứ tư (fourth)
This pattern is used for ranking and sequence.
However, certain common expressions follow their own conventions, especially days of the week.

Fractions and Parts

Vietnamese can express fractions with structures involving phần (part).
For example:
một phần hai (one half)
một phần ba (one third)
hai phần ba (two thirds)
In everyday contexts, specialized expressions may also be used depending on the type of quantity.

Numbers and Demonstratives

Numbers and classifiers can combine with demonstratives.
For example:
hai cái bàn này (these two tables)
ba người đó (those three people)
bốn quyển sách này (these four books)
The general order is:
number + classifier + noun + demonstrative

Quantifiers and Noun Form

Vietnamese nouns normally remain unchanged after quantifiers.
Compare:
một người (one person)
hai người (two people)
nhiều người (many people)
The noun người does not acquire a plural ending.

Common Quantity Expressions

Useful forms include:
một (one; a)
nhiều (many; much)
ít (few; little)
một ít (a little)
vài (a few)
một số (some)
mỗi (each; every)
mọi (every; all)
tất cả (all)
cả hai (both)
đủ (enough)
thêm (more; additional)
quá nhiều (too much; too many)
khoảng (approximately)
bao nhiêu (how much; how many)

Key Point

Vietnamese numbers and quantifiers do not cause nouns to change form. Exact numbers commonly follow the pattern number + classifier + noun, as in ba quyển sách (three books) and hai con mèo (two cats). Indefinite quantities are expressed with words such as nhiều (many; much), ít (few; little), vài (a few), mỗi (each; every), and tất cả (all). Learning these quantifiers together with the classifier system is essential for expressing quantity naturally in Vietnamese.

Vietnamese Adjectives

Vietnamese adjectives are relatively straightforward because they do not change form according to gender, number, or person. The same adjective can describe one person, several people, masculine or feminine nouns, and subjects of any grammatical person without changing its ending.

Position of Adjectives

In most ordinary noun phrases, Vietnamese adjectives follow the noun they describe.
For example:
nhà đẹp (beautiful house)
xe mới (new car)
người trẻ (young person)
sách hay (interesting book)
This noun + adjective order is one of the most important patterns to remember when building Vietnamese phrases.

Adjectives as Predicates

Vietnamese adjectives can often function directly as the main predicate of a sentence. A separate verb meaning to be is normally unnecessary.
For example:
Nhà đẹp. (The house is beautiful.)
Cô ấy cao. (She is tall.)
Trời nóng. (The weather is hot.)
The verb là (to be) is generally not used before ordinary adjectives in this type of sentence. Therefore, Cô ấy cao (She is tall) is the natural basic structure.

Common Vietnamese Adjectives

Some useful everyday adjectives include:
đẹp (beautiful)
tốt (good)
xấu (bad; ugly)
lớn (big; large)
nhỏ (small)
cao (tall; high)
thấp (short; low)
mới (new)
cũ (old; used)
nhanh (fast)
chậm (slow)
dễ (easy)
khó (difficult)
For example:
một căn phòng lớn (a large room)
một chiếc xe mới (a new car)
một bài tập khó (a difficult exercise)

Making Adjectives Stronger

Vietnamese uses separate words to express degree rather than changing the adjective itself.
One of the most common is rất (very).
For example:
rất đẹp (very beautiful)
rất tốt (very good)
rất khó (very difficult)
In a complete sentence:
Món ăn này rất ngon. (This dish is very delicious.)
Other useful degree words include:
khá (quite; fairly)
hơi (slightly; somewhat)
quá (too; extremely)
Examples:
khá tốt (quite good)
hơi lạnh (slightly cold)
quá đắt (too expensive)

Comparative Adjectives

Vietnamese normally forms comparisons with hơn (more; than). The adjective itself does not change.
The basic pattern is:
adjective + hơn
For example:
cao hơn (taller)
nhanh hơn (faster)
đẹp hơn (more beautiful)
A complete comparison can be formed as:
Anh ấy cao hơn tôi. (He is taller than me.)
Xe này rẻ hơn xe kia. (This car is cheaper than that car.)
Unlike languages with comparative adjective endings, Vietnamese keeps the original adjective unchanged.

Superlatives

Superlative meaning is commonly expressed with nhất (most; -est).
The usual pattern is:
adjective + nhất
For example:
cao nhất (tallest; highest)
đẹp nhất (most beautiful)
tốt nhất (best)
nhanh nhất (fastest)
In a sentence:
Đây là nhà hàng tốt nhất. (This is the best restaurant.)

Equality

To say that two things are equally similar in a particular quality, Vietnamese commonly uses bằng (equal to; as...as).
For example:
Anh ấy cao bằng tôi. (He is as tall as me.)
Xe này nhanh bằng xe đó. (This car is as fast as that car.)
Another common structure uses như (like; as):
đẹp như tranh (beautiful like a painting)

Negative Adjectives

Adjectives can be negated with không (not).
For example:
không đẹp (not beautiful)
không khó (not difficult)
không đắt (not expensive)
In complete sentences:
Bài này không khó. (This exercise is not difficult.)
Khách sạn này không đắt. (This hotel is not expensive.)
Because adjectives can function directly as predicates, không is placed before the adjective just as it is placed before many verbs.

Adjectives with Demonstratives

When an adjective and a demonstrative appear with the same noun, the adjective normally comes before the demonstrative.
For example:
ngôi nhà đẹp này (this beautiful house)
chiếc xe mới đó (that new car)
người trẻ kia (that young person over there)
The general pattern is:
noun + adjective + demonstrative

More Than One Adjective

A noun can be followed by more than one adjective or descriptive element.
For example:
một ngôi nhà lớn và đẹp (a large and beautiful house)
một người trẻ, thông minh và thân thiện (a young, intelligent, and friendly person)
The conjunction và (and) is commonly used to connect adjectives.

Adjectives and Intensification

Vietnamese frequently places certain degree expressions after adjectives as well as before them. quá (too; so; extremely) is especially common after an adjective in everyday speech.
For example:
Đẹp quá! (So beautiful!)
Nóng quá! (So hot!)
Đắt quá! (Too expensive!)
This construction is extremely common in spoken Vietnamese and is often used to express a strong reaction.

Adjectives in Everyday Vietnamese

Many adjectives can describe both physical characteristics and more abstract qualities depending on context.
For example:
cao can mean tall when describing a person and high when describing a building, price, or level.
nặng (heavy) can describe physical weight but can also appear in broader expressions.
nhẹ (light) can describe weight, intensity, or degree.
Context therefore plays an important role in determining the most natural English translation.

Key Point

Vietnamese adjectives are simple in form because they do not agree with nouns and do not require gender, number, or person endings. The most important patterns are learning that adjectives usually follow nouns, that they can function directly as predicates, and that comparison is expressed with separate words such as hơn (more; than) and nhất (most). Instead of changing đẹp (beautiful), Vietnamese simply builds combinations such as rất đẹp (very beautiful), đẹp hơn (more beautiful), and đẹp nhất (most beautiful).

Vietnamese Pronouns

Vietnamese pronouns are one of the most distinctive parts of the language because speakers often choose forms according to age, relationship, social position, familiarity, and situation. Instead of relying on a small fixed set of words equivalent to I, you, he, and she, Vietnamese frequently uses kinship terms and titles as pronouns.

Basic Personal Pronouns

Some common personal pronouns include:
tôi (I; me)
mình (I; me; oneself, depending on context)
bạn (you; friend)
họ (they; them)
nó (he; she; it, usually for children, animals, or informal contexts)
chúng tôi (we; us, excluding the listener)
chúng ta (we; us, including the listener)
These forms are useful, but they do not cover all ordinary situations. In everyday conversation, Vietnamese speakers very often use relationship terms instead.

Tôi

tôi (I; me) is a neutral and widely understood first-person pronoun. It is common in formal situations, conversations between adults who are not close, writing, interviews, public communication, and many beginner language materials.
For example:
Tôi là giáo viên. (I am a teacher.)
Tôi sống ở Hà Nội. (I live in Hanoi.)
Tôi thích cà phê. (I like coffee.)
Although tôi is safe in many contexts, close friends and family members often use other forms that better reflect their relationship.

Bạn

bạn (you; friend) is commonly taught as a general word for you. It works naturally between people of similar age in friendly or relatively neutral situations.
For example:
Bạn tên là gì? (What is your name?)
Bạn khỏe không? (Are you well?)
However, Vietnamese does not normally use bạn for every person regardless of age or relationship. Speaking to an older person with bạn can sound inappropriate in many situations, so kinship-based forms are often preferred.

Kinship Terms as Pronouns

Vietnamese commonly uses family relationship words as personal pronouns even when the speakers are not actually related.
Important forms include:
anh (older brother; older male)
chị (older sister; older female)
em (younger sibling; younger person)
cô (aunt; woman of a certain older generation; female teacher)
chú (younger uncle; adult man younger than one's parents)
bác (older uncle or aunt; older adult)
ông (grandfather; older man)
bà (grandmother; older woman)
These words can mean both the person being addressed and the speaker, depending on the relationship.
For example, a younger person speaking to a slightly older man may call him anh and refer to themselves as em:
Anh có khỏe không? (Are you well?)
Em khỏe. (I am well.)
The same word therefore does not have one permanent grammatical person. Its meaning depends on who is speaking to whom.

Anh and Em

The pair anh and em is extremely common.
A younger person may address an older male as anh and refer to themselves as em:
Anh đi đâu? (Where are you going?)
Em đi làm. (I am going to work.)
An older male speaking to a younger person may use anh for himself and em for the other person:
Anh hiểu rồi. (I understand now.)
Em có muốn đi không? (Do you want to go?)
This means that anh can correspond to either I or you depending on the speaker.

Chị and Em

A similar relationship exists between chị (older sister; older female) and em.
A younger person may say:
Chị làm việc ở đâu? (Where do you work?)
The older woman may answer:
Chị làm việc ở bệnh viện. (I work at a hospital.)
Again, chị can refer either to the person being addressed or to the speaker herself.

Family Relationships

Within families, kinship terms are normally used very extensively.
A child may call their mother mẹ (mother) and father bố (father) or ba (father, especially common in southern usage).
Parents may refer to themselves using the same family titles:
Mẹ đi làm. (Mom is going to work; I am going to work, said by the mother to her child.)
Bố về rồi. (Dad is home now; I am home now, said by the father.)
Children commonly refer to themselves as con (child) when speaking to parents or older family members:
Con cảm ơn mẹ. (Thank you, Mom.)

Mình

mình has several common uses and is strongly dependent on context.
It can mean I or me in informal speech:
Mình không biết. (I don't know.)
It can also refer to oneself:
tự mình (by oneself)
Between close partners or spouses, mình may also function as an intimate term of address.
Because it has several uses, learners should pay attention to the relationship between the speakers rather than assigning it one fixed English translation.

Tao and Mày

Very informal pronouns include:
tao (I; me)
mày (you)
These forms are used between certain very close friends, in rough or highly informal speech, and in hostile situations.
For example:
Tao biết. (I know.)
Mày đi đâu? (Where are you going?)
Learners should use these forms cautiously. In the wrong situation they can sound disrespectful or aggressive.

Nó

nó can mean he, she, or it. It is often used for children, animals, objects, or people discussed in informal contexts.
For example:
Nó đang ngủ. (He/She is sleeping.)
Con mèo đâu? Nó ở ngoài. (Where is the cat? It is outside.)
When referring respectfully to adults, Vietnamese normally prefers kinship terms, names, or titles rather than nó.

Third-Person Reference

Vietnamese does not require separate ordinary pronouns corresponding exactly to English he and she. Instead, speakers often use a kinship term plus ấy (that; that person).
Common examples include:
anh ấy (he; that man)
chị ấy (she; that woman)
cô ấy (she; that woman)
ông ấy (he; that older man)
bà ấy (she; that older woman)
For example:
Anh ấy là bác sĩ. (He is a doctor.)
Cô ấy sống ở Đà Nẵng. (She lives in Da Nang.)
The choice of term reflects the apparent age and social relationship of the person being discussed.

We: Chúng Tôi and Chúng Ta

Vietnamese makes an important distinction between two common words for we.
chúng tôi means we but normally excludes the person being addressed.
chúng ta means we and includes the listener.
For example:
Chúng tôi sống ở Việt Nam. (We live in Vietnam.)
This normally refers to the speaker's group, not the listener.
By contrast:
Chúng ta đi nhé. (Let's go.)
includes both the speaker and the listener.
This distinction is important because it can change who is understood to be part of the group.

Other Plural Pronouns

Vietnamese can form plural personal expressions with words such as chúng and các.
Examples include:
chúng tôi (we; us)
chúng ta (we; us, including the listener)
chúng nó (they; them, informal)
các bạn (you, plural)
các anh (you older men; you gentlemen)
các chị (you older women; you ladies)
The exact form depends on the people involved and the level of formality.

Pronouns and Names

Vietnamese speakers frequently use personal names where other languages might use pronouns.
For example, a person named Lan may say:
Lan không biết. (I don't know, said by Lan in an appropriate social context.)
Someone speaking to Lan may ask:
Lan có đi không? (Are you going, Lan?)
Using names in this way is especially common in familiar relationships and can sound more natural than repeatedly using a neutral pronoun.

Titles as Pronouns

Professional and social titles can also be used as forms of address.
Examples include:
thầy (male teacher)
cô (female teacher)
bác sĩ (doctor)
A student may address a teacher as thầy or cô rather than using a general word for you.
For example:
Thầy có khỏe không? (Are you well, teacher?)
Cô có thể giúp em không? (Can you help me, teacher?)
Titles can therefore function grammatically much like pronouns.

Pronouns and Politeness

Choosing the correct pronoun is an important part of Vietnamese politeness. Speakers usually consider relative age, status, intimacy, and family-like relationships before deciding how to address one another.
Polite particles often accompany these forms. One of the most important is ạ (respectful sentence particle):
Cháu chào bác ạ. (Hello, said respectfully by a younger person to an older adult.)
Vâng ạ. (Yes, respectfully.)
Another common respectful response is dạ (yes; respectful acknowledgement).
These words help create a polite tone even though they are not pronouns themselves.

Omitting Pronouns

Vietnamese can omit pronouns when the subject or object is already clear from context.
For example:
Ăn chưa? (Have you eaten yet?)
The sentence contains no explicit word for you, but the meaning is clear from the conversation.
Similarly:
Biết rồi. (I know already; understood.)
The subject is understood rather than stated.
This kind of omission is extremely common in natural spoken Vietnamese.

Reflexive Expressions

Vietnamese commonly uses tự (self; by oneself) to express reflexive meaning.
Examples:
tự làm (to do by oneself)
tự học (to study by oneself; self-study)
tự giới thiệu (to introduce oneself)
For example:
Tôi tự học tiếng Việt. (I study Vietnamese by myself.)
The form of the pronoun itself does not change.

Possessive Pronouns

Vietnamese usually expresses possession with của (of; belonging to) rather than special possessive pronoun forms.
For example:
của tôi (mine)
của bạn (yours)
của anh ấy (his)
của cô ấy (hers)
In a noun phrase:
nhà của tôi (my house)
xe của cô ấy (her car)
When the relationship is obvious, của may sometimes be omitted.

Choosing the Right Pronoun

There is often more than one grammatically possible way to address someone. A young adult speaking to a slightly older man may use anh, while the same person may use chú for a man closer to their parents' generation and ông for a much older man.
Likewise, chị, cô, and bà can indicate different relative generations when addressing women.
The system is flexible rather than mechanical. Native speakers adjust their choices according to context, respect, and social relationship.

Key Point

Vietnamese pronouns are not difficult because of complicated grammatical forms; they are challenging because they encode social relationships. Words such as tôi (I), bạn (you), anh (older male), chị (older female), and em (younger person) must be understood in context. The same kinship term can mean I in one conversation and you in another. Learning natural Vietnamese therefore means learning not only who is speaking, but also how the speakers relate to one another.

Vietnamese Prepositions

Vietnamese uses a range of short words to express relationships such as place, direction, time, possession, accompaniment, purpose, and origin. These words are often described as prepositions for learners because they perform many of the same functions as prepositions in other languages. Vietnamese prepositions do not change form, and their meaning is usually determined by their position and context.

Basic Preposition Structure

A Vietnamese prepositional phrase commonly follows this pattern:
preposition + noun or pronoun
For example:
ở nhà (at home)
từ Hà Nội (from Hanoi)
với bạn (with a friend; with you)
cho tôi (for me; to me)
về Việt Nam (to Vietnam; about Vietnam, depending on context)
These phrases can appear after verbs or at the beginning of sentences.

Ở

ở is one of the most important Vietnamese prepositions. It commonly expresses location and can mean at, in, or on depending on context.
Examples:
ở nhà (at home)
ở Việt Nam (in Vietnam)
ở trường (at school)
ở Hà Nội (in Hanoi)
In complete sentences:
Tôi sống ở Hà Nội. (I live in Hanoi.)
Cô ấy đang ở nhà. (She is at home.)
Vietnamese normally uses the same ở for many relationships that require different prepositions in English.

Trong

trong means in, inside, or within and emphasizes being inside something.
For example:
trong nhà (inside the house)
trong phòng (in the room)
trong hộp (inside the box)
trong thành phố (within the city)
Compare:
ở nhà (at home)
trong nhà (inside the house)
ở gives a general location, while trong emphasizes the interior of a place or object.

Ngoài

ngoài commonly means outside, outside of, or beyond.
Examples:
ngoài nhà (outside the house)
ngoài đường (outside; in the street)
ngoài thành phố (outside the city)
For example:
Anh ấy đang đứng ngoài nhà. (He is standing outside the house.)
Ngoài Việt Nam, tiếng Việt còn được sử dụng ở nhiều nước. (Outside Vietnam, Vietnamese is also used in many countries.)

Trên

trên usually means on, above, or over.
Examples:
trên bàn (on the table)
trên tường (on the wall)
trên trời (in the sky)
For example:
Sách ở trên bàn. (The book is on the table.)
Bức tranh ở trên tường. (The picture is on the wall.)
trên can therefore describe both contact with a surface and a higher position.

Dưới

dưới means under, below, or beneath.
Examples:
dưới bàn (under the table)
dưới giường (under the bed)
dưới đất (on/below the ground)
For example:
Con mèo ở dưới bàn. (The cat is under the table.)
dưới is the natural opposite of trên in many spatial expressions.

Trước and Sau

trước means before, in front of, or ahead of, depending on context.
Examples:
trước nhà (in front of the house)
trước giờ học (before class)
trước bữa tối (before dinner)
sau means after or behind:
sau nhà (behind the house)
sau giờ làm (after work)
sau bữa ăn (after the meal)
For example:
Xe ở trước nhà. (The car is in front of the house.)
Tôi học tiếng Việt sau giờ làm. (I study Vietnamese after work.)
The same words can therefore express both spatial and temporal relationships.

Giữa

giữa means between, among, or in the middle of.
Examples:
giữa hai ngôi nhà (between two houses)
giữa thành phố (in the middle of the city)
giữa bạn bè (among friends)
For example:
Khách sạn nằm giữa nhà ga và bệnh viện. (The hotel is between the station and the hospital.)
When two elements are explicitly mentioned, giữa ... và ... (between ... and ...) is a common structure.

Bên

bên means side and appears in many useful location expressions.
Examples include:
bên trái (on the left)
bên phải (on the right)
bên cạnh (next to; beside)
bên trong (inside)
bên ngoài (outside)
For example:
Ngân hàng ở bên trái. (The bank is on the left.)
Nhà hàng ở bên cạnh khách sạn. (The restaurant is next to the hotel.)
These combinations are especially useful when asking for or giving directions.

Gần and Xa

gần means near or close to.
For example:
gần nhà (near the house)
gần trường (near the school)
Khách sạn ở gần sân bay. (The hotel is near the airport.)
xa means far from or distant:
xa nhà (far from home)
xa trung tâm (far from the center)
A phrase with xa may also use cách when describing distance:
Nhà tôi cách trường hai kilômét. (My house is two kilometers from the school.)

Từ

từ is an extremely common preposition meaning from or since.
It can indicate origin:
từ Việt Nam (from Vietnam)
từ Hà Nội (from Hanoi)
It can also indicate a starting point in time:
từ hôm nay (from today)
từ năm 2020 (since 2020; from the year 2020)
For example:
Tôi đến từ Ba Lan. (I come from Poland.)
Cửa hàng mở từ tám giờ. (The shop is open from eight o'clock.)

Từ ... Đến

Vietnamese commonly uses từ ... đến ... to express from ... to ... in both time and space.
Examples:
từ Hà Nội đến Huế (from Hanoi to Hue)
từ thứ Hai đến thứ Sáu (from Monday to Friday)
từ tám giờ đến mười giờ (from eight o'clock to ten o'clock)
For example:
Tôi làm việc từ thứ Hai đến thứ Sáu. (I work from Monday to Friday.)
This structure is highly regular and useful in everyday communication.

Đến

đến commonly expresses movement toward a destination and can mean to, until, or arrive at depending on its grammatical role.
Examples:
đến trường (to school)
đến Hà Nội (to Hanoi)
đến đây (to here; come here)
For example:
Tôi đi đến bệnh viện. (I go to the hospital.)
In natural Vietnamese, đi (to go) can often be followed directly by the destination:
Tôi đi Hà Nội. (I am going to Hanoi.)
The exact use of đến depends on the verb and context.

Về

về has several important uses. With movement, it often means to return to, toward, or back to.
Examples:
về nhà (go home; return home)
về Việt Nam (return/go to Vietnam)
For example:
Tôi về nhà lúc sáu giờ. (I go home at six o'clock.)
về can also mean about when introducing a topic:
nói về Việt Nam (to talk about Vietnam)
sách về lịch sử (a book about history)
Chúng tôi nói về công việc. (We talk about work.)

Với

với usually means with and expresses accompaniment, association, or interaction.
Examples:
với bạn (with a friend; with you)
với gia đình (with the family)
đi với tôi (go with me)
For example:
Tôi đi ăn với bạn. (I am going to eat with a friend.)
Cô ấy sống với gia đình. (She lives with her family.)
với also appears with many verbs that describe relationships between people or things.

Cùng

cùng can mean together, together with, or the same depending on context.
For example:
đi cùng bạn (go together with a friend)
làm việc cùng nhau (work together)
Chúng ta cùng đi nhé. (Let's go together.)
Although cùng and với can both occur in expressions involving accompaniment, cùng often emphasizes doing something together.

Cho

cho is one of the most versatile Vietnamese words. It frequently means for or to when something is given, done, or intended for another person.
Examples:
cho tôi (for me; to me)
cho trẻ em (for children)
quà cho bạn (a gift for a friend)
For example:
Tôi mua quà cho mẹ. (I buy a gift for my mother.)
Anh ấy đưa sách cho tôi. (He gives the book to me.)
cho can also function as a verb meaning to give:
Tôi cho anh ấy một cuốn sách. (I give him a book.)
Its exact function depends on the sentence structure.

Của

của expresses possession, belonging, or association and is commonly translated as of or by an English possessive form.
Examples:
nhà của tôi (my house)
xe của anh ấy (his car)
tên của cô ấy (her name)
thủ đô của Việt Nam (the capital of Vietnam)
For example:
Đây là sách của tôi. (This is my book.)
In everyday Vietnamese, của can sometimes be omitted when the relationship is obvious:
mẹ tôi (my mother)
nhà tôi (my house; my home)

Bằng

bằng can mean by, with, or using when it indicates a method, means, or instrument.
Examples:
bằng xe buýt (by bus)
bằng tiếng Việt (in Vietnamese; using Vietnamese)
bằng tay (by hand)
For example:
Tôi đi làm bằng xe buýt. (I go to work by bus.)
Anh ấy viết bằng tiếng Việt. (He writes in Vietnamese.)
bằng is also used in comparisons to mean equal to or as ... as:
cao bằng tôi (as tall as me)

Theo

theo can mean according to, following, along, or in accordance with.
Examples:
theo tôi (according to me; in my opinion)
theo luật (according to the law)
theo kế hoạch (according to the plan)
For example:
Theo tôi, đây là một ý kiến hay. (In my opinion, this is a good idea.)
Chúng tôi làm việc theo kế hoạch. (We work according to the plan.)
It can also express physical following:
Đi theo tôi. (Follow me.)

Về and Đối Với

When discussing a topic, về is very common:
một bài viết về Việt Nam (an article about Vietnam)
nói về gia đình (talk about family)
đối với means regarding, toward, or for when expressing a relationship or point of view:
đối với tôi (for me; as far as I am concerned)
đối với trẻ em (for children; regarding children)
For example:
Điều này rất quan trọng đối với tôi. (This is very important to me.)

Vì

vì means because of or can introduce a reason.
For example:
vì công việc (because of work)
vì thời tiết (because of the weather)
Tôi ở nhà vì trời mưa. (I stay home because it is raining.)
When followed by a complete clause, vì functions much like because:
Tôi không đi vì tôi mệt. (I am not going because I am tired.)

Để

để commonly means in order to or for the purpose of and introduces a purpose.
Examples:
để học (in order to study)
để làm việc (in order to work)
Tôi đến Việt Nam để học tiếng Việt. (I come to Vietnam to study Vietnamese.)
để is therefore extremely common when explaining why an action is performed.

Không Có Preposition Changes

Vietnamese prepositions do not change form according to the noun or pronoun that follows them.
For example:
với tôi (with me)
với bạn (with you)
với họ (with them)
The word với remains unchanged.
Similarly:
cho tôi (for me)
cho cô ấy (for her)
cho chúng tôi (for us)
There are no case endings to memorize.

Prepositional Phrases at the Beginning of a Sentence

Vietnamese frequently places time, place, and other contextual phrases at the beginning of a sentence.
For example:
Ở Việt Nam, tiếng Việt là ngôn ngữ chính thức. (In Vietnam, Vietnamese is the official language.)
Sau giờ làm, tôi học tiếng Việt. (After work, I study Vietnamese.)
Với bạn bè, anh ấy rất vui vẻ. (With friends, he is very cheerful.)
This structure is particularly common when the speaker wants to establish the setting before giving the main information.

Location Expressions

Vietnamese often combines ở with more specific location words.
For example:
ở trong nhà (inside the house)
ở ngoài sân (outside in the yard)
ở trên bàn (on the table)
ở dưới ghế (under the chair)
ở bên cạnh trường (next to the school)
In many contexts, ở can be omitted when the location relationship is already clear:
Sách trên bàn. (The book is on the table.)
However, using ở often makes the location structure more explicit.

Asking Where Something Is

A very common question word is ở đâu (where).
For example:
Bạn ở đâu? (Where are you?; Where do you live?)
Nhà hàng ở đâu? (Where is the restaurant?)
Bạn làm việc ở đâu? (Where do you work?)
Answers frequently use the same location structures:
Tôi ở nhà. (I am at home.)
Nhà hàng ở gần khách sạn. (The restaurant is near the hotel.)

Asking Where Someone Comes From

Origin is commonly expressed with từ:
Bạn đến từ đâu? (Where do you come from?)
A possible answer is:
Tôi đến từ Ý. (I come from Italy.)
The combination đến từ (to come from) is especially common when talking about a person's place or country of origin.

Prepositions and Movement

Vietnamese distinguishes between general location and movement through words such as ở, đến, về, vào, and ra.
ở indicates location:
Tôi ở nhà. (I am at home.)
đến indicates movement toward:
Tôi đến trường. (I go/come to school.)
về often indicates movement back or toward home:
Tôi về nhà. (I go home.)
vào means into; enter:
đi vào nhà (go into the house)
ra means out; go out:
đi ra ngoài (go outside)
These directional words are extremely common in spoken Vietnamese.

Vào

vào usually expresses movement inward or toward an interior.
Examples:
vào nhà (into the house)
vào phòng (into the room)
Đi vào đây. (Come/go in here.)
It can also be used with time:
vào thứ Hai (on Monday)
vào buổi sáng (in the morning)
The correct interpretation depends on context.

Ra

ra generally expresses movement outward or away from an interior.
Examples:
ra ngoài (go outside)
ra khỏi nhà (go out of the house)
Anh ấy đi ra ngoài. (He goes outside.)
ra is one of several Vietnamese directional words that often follow a movement verb such as đi (to go).

Khỏi

khỏi can mean out of, away from, or from when emphasizing departure from a place.
For example:
ra khỏi nhà (go out of the house)
rời khỏi thành phố (leave the city)
Anh ấy bước ra khỏi phòng. (He steps out of the room.)
It frequently combines with movement verbs.

Qua

qua can mean through, across, past, or via.
Examples:
qua đường (across the street)
qua cầu (across the bridge)
đi qua công viên (go through the park)
For example:
Chúng tôi đi qua trung tâm thành phố. (We go through the city center.)
It also has several non-spatial uses that are best learned in context.

Prepositions and Time

Several common prepositional words also express time:
trước (before)
sau (after)
từ (from; since)
đến (until; to)
trong (during; within)
Examples:
trước bữa sáng (before breakfast)
sau giờ học (after class)
trong một tuần (within/during one week)
từ sáng đến tối (from morning until evening)
Vietnamese often uses these words without changing the form of the time expression.

Words That Can Have Several Functions

Many Vietnamese words commonly taught as prepositions can also function as verbs, nouns, adverbs, or other grammatical elements.
For example, cho can mean for/to but also to give. đến can mean to but can also mean to arrive. trong can mean inside and can also function as a noun meaning the inside in certain structures.
For learners, the most useful approach is to learn these words through complete phrases rather than trying to assign each one a single English equivalent.

Common Prepositional Expressions

Useful combinations include:
ở nhà (at home)
ở trường (at school)
trong phòng (in the room)
trên bàn (on the table)
dưới ghế (under the chair)
bên cạnh nhà (next to the house)
gần sân bay (near the airport)
từ Việt Nam (from Vietnam)
đến Hà Nội (to Hanoi)
về nhà (home; back home)
với bạn (with a friend)
cho tôi (for me)
của tôi (mine; my)
bằng xe buýt (by bus)
về lịch sử (about history)
vì công việc (because of work)

Key Point

Vietnamese prepositions are generally simple in form because they never change according to gender, number, or case. The main task is learning which relationship each word expresses and how it combines with verbs and nouns. Core forms such as ở (at; in), trong (inside), trên (on; above), dưới (under), từ (from), đến (to), với (with), cho (for; to), của (of), and về (toward; about) appear constantly in everyday Vietnamese and provide the foundation for describing place, movement, time, possession, and relationships.

Vietnamese Adverbs

Vietnamese adverbs are flexible words and expressions that modify verbs, adjectives, other adverbs, or entire sentences. They can express time, frequency, manner, degree, certainty, place, sequence, and many other meanings. Vietnamese adverbs do not change form according to person, number, gender, or tense, so the main challenge is learning their position and function within the sentence.

Basic Adverb Position

Vietnamese adverbs can appear before or after the word they modify, depending on their meaning.
For example:
Tôi thường đọc sách. (I often read books.)
Anh ấy chạy nhanh. (He runs quickly.)
Cô ấy rất thông minh. (She is very intelligent.)
In these examples, thường (often) comes before the verb, nhanh (quickly) follows the verb, and rất (very) comes before the adjective.

Adverbs of Time

Vietnamese has many common words that indicate when an action happens.
Important examples include:
hôm nay (today)
hôm qua (yesterday)
ngày mai (tomorrow)
bây giờ (now)
lúc này (at this moment)
sớm (early)
muộn (late)
trước đây (previously; in the past)
sau này (later; in the future)
For example:
Hôm nay tôi làm việc ở nhà. (Today I work at home.)
Ngày mai chúng tôi đi Hà Nội. (Tomorrow we are going to Hanoi.)
Bây giờ cô ấy đang học. (She is studying now.)
Time expressions frequently appear at the beginning of a sentence, although they may also appear later.

Hôm Nay, Hôm Qua, and Ngày Mai

Three of the most useful Vietnamese time expressions are:
hôm nay (today)
hôm qua (yesterday)
ngày mai (tomorrow)
For example:
Hôm qua tôi ở nhà. (Yesterday I was at home.)
Hôm nay tôi đi làm. (Today I am going to work.)
Ngày mai tôi nghỉ. (Tomorrow I am off.)
Because Vietnamese verbs do not change form for tense, these time expressions are particularly important for showing when an action takes place.

Bây Giờ

bây giờ means now or at the moment.
For example:
Bây giờ tôi rất bận. (I am very busy now.)
Bạn đang làm gì bây giờ? (What are you doing now?)
It can occur at the beginning or end of the sentence depending on emphasis.

Rồi

rồi is an extremely common Vietnamese word. Among its most frequent uses, it can indicate that something has already happened or that a change of state has been completed.
For example:
Tôi ăn rồi. (I have already eaten.)
Anh ấy về rồi. (He has gone home already.)
Trời tối rồi. (It is dark now; it has become dark.)
The exact translation depends heavily on context.

Đã

đã is commonly used before a verb to indicate that an action is completed or belongs to an earlier time.
For example:
Tôi đã ăn. (I ate; I have eaten.)
Cô ấy đã về nhà. (She went home; she has gone home.)
Chúng tôi đã gặp nhau. (We have met.)
Vietnamese does not require đã every time an action happened in the past. If the time is already obvious from context, it may be unnecessary.
For example:
Hôm qua tôi đi làm. (Yesterday I went to work.)
The expression hôm qua already establishes the past time.

Đang

đang usually indicates that an action is in progress.
It normally appears before the verb:
đang ăn (eating; currently eating)
đang học (studying)
đang làm việc (working)
For example:
Tôi đang đọc sách. (I am reading a book.)
Cô ấy đang ngủ. (She is sleeping.)
Họ đang nói chuyện. (They are talking.)
The word đang is especially useful when emphasizing that something is happening at the present moment.

Sẽ

sẽ commonly indicates a future action or situation.
For example:
Tôi sẽ gọi cho bạn. (I will call you.)
Ngày mai chúng tôi sẽ đi Huế. (Tomorrow we will go to Hue.)
Anh ấy sẽ đến lúc tám giờ. (He will arrive at eight o'clock.)
As with đã, sẽ is not always necessary when a future time expression already makes the meaning clear.

Adverbs of Frequency

Frequency adverbs indicate how often something happens.
Common forms include:
luôn luôn (always)
thường (often; usually)
thường xuyên (frequently; regularly)
đôi khi (sometimes)
thỉnh thoảng (occasionally)
hiếm khi (rarely)
không bao giờ (never)
These generally appear before the main verb.
For example:
Tôi thường uống cà phê. (I usually drink coffee.)
Cô ấy luôn luôn đến đúng giờ. (She always arrives on time.)
Chúng tôi đôi khi ăn ở nhà hàng. (We sometimes eat at restaurants.)

Luôn and Luôn Luôn

luôn and luôn luôn both express the idea of always or consistently.
For example:
Anh ấy luôn đúng giờ. (He is always punctual.)
Cô ấy luôn luôn giúp tôi. (She always helps me.)
The repeated form luôn luôn can give the expression additional emphasis.

Thường

thường means often or usually.
For example:
Tôi thường đi bộ đến trường. (I usually walk to school.)
Bạn thường làm gì cuối tuần? (What do you usually do on weekends?)
It is one of the most common Vietnamese adverbs of frequency and normally appears before the verb.

Thường Xuyên

thường xuyên means frequently or regularly and often emphasizes repeated or habitual activity.
For example:
Tôi thường xuyên tập thể dục. (I exercise regularly.)
Cô ấy thường xuyên đi công tác. (She frequently travels for work.)
It can sound slightly more deliberate or systematic than simple thường.

Đôi Khi and Thỉnh Thoảng

Both đôi khi and thỉnh thoảng can mean sometimes or occasionally.
For example:
Đôi khi tôi làm việc ở nhà. (Sometimes I work from home.)
Thỉnh thoảng chúng tôi đi xem phim. (Occasionally we go to the cinema.)
These expressions can appear at the beginning of a sentence or before the main verb.

Hiếm Khi

hiếm khi means rarely or seldom.
For example:
Tôi hiếm khi uống rượu. (I rarely drink alcohol.)
Anh ấy hiếm khi đến muộn. (He is rarely late.)
Because hiếm khi already contains a negative-like idea of low frequency, Vietnamese normally does not add không before it.

Không Bao Giờ

không bao giờ means never.
For example:
Tôi không bao giờ hút thuốc. (I never smoke.)
Cô ấy không bao giờ đến muộn. (She is never late.)
The structure combines không (not) with bao giờ (ever; when).

Adverbs of Manner

Adverbs of manner describe how an action is performed.
Vietnamese often uses an adjective after the verb to express this meaning.
For example:
chạy nhanh (run quickly)
đi chậm (walk slowly)
nói nhỏ (speak quietly)
làm việc chăm chỉ (work hard)
In complete sentences:
Anh ấy chạy rất nhanh. (He runs very quickly.)
Cô ấy nói chậm. (She speaks slowly.)
Họ làm việc chăm chỉ. (They work hard.)
There is usually no special adverb ending corresponding to English -ly.

Nhanh and Chậm

nhanh means fast or quickly, while chậm means slow or slowly.
For example:
Anh ấy lái xe nhanh. (He drives fast.)
Xin nói chậm. (Please speak slowly.)
The same Vietnamese form can function as an adjective or as an adverb depending on its position and context.

Tốt

tốt primarily means good, but in some contexts it can contribute an adverbial meaning similar to well.
For example:
Anh ấy làm việc rất tốt. (He works very well.)
Here tốt describes the quality of the action rather than a noun.
Vietnamese frequently uses the same word for adjectival and adverbial meanings without changing its form.

Adverbs of Degree

Degree adverbs indicate how strong or intense a quality or action is.
Common examples include:
rất (very)
khá (quite; fairly)
hơi (slightly; somewhat)
quá (too; extremely)
cực kỳ (extremely)
vô cùng (extremely; immensely)
For example:
rất đẹp (very beautiful)
khá tốt (quite good)
hơi khó (slightly difficult)
quá đắt (too expensive)
cực kỳ quan trọng (extremely important)

Rất

rất is one of the most common degree adverbs in Vietnamese and normally appears before an adjective.
For example:
rất đẹp (very beautiful)
rất lớn (very large)
rất ngon (very delicious)
rất quan trọng (very important)
In a sentence:
Khách sạn này rất đẹp. (This hotel is very beautiful.)
Món ăn này rất ngon. (This dish is very delicious.)

Khá

khá commonly means quite, fairly, or rather.
For example:
khá dễ (fairly easy)
khá tốt (quite good)
khá xa (quite far)
Bài này khá khó. (This exercise is quite difficult.)
The precise strength of khá depends on context.

Hơi

hơi means slightly, a little, or somewhat.
For example:
hơi lạnh (a little cold)
hơi mệt (slightly tired)
hơi đắt (a little expensive)
In a sentence:
Hôm nay tôi hơi mệt. (I am a little tired today.)
It is very common when softening a negative or critical statement.

Quá

quá can mean too, very, so, or extremely depending on context.
Before or after an adjective, it can express excessive or strong degree:
quá đắt (too expensive)
quá khó (too difficult)
In conversational exclamations, it often comes after the adjective:
Đẹp quá! (So beautiful!)
Ngon quá! (So delicious!)
Nóng quá! (So hot!)
This post-adjective use is extremely common in spoken Vietnamese.

Cực Kỳ

cực kỳ means extremely and gives strong emphasis.
For example:
cực kỳ quan trọng (extremely important)
cực kỳ đẹp (extremely beautiful)
cực kỳ khó (extremely difficult)
It is stronger than ordinary rất in many contexts.

Vô Cùng

vô cùng also means extremely, immensely, or incredibly and often has an emphatic or somewhat expressive quality.
For example:
vô cùng quan trọng (extremely important)
vô cùng hạnh phúc (extremely happy)
It is especially common in formal or expressive language.

More and Less

Vietnamese commonly uses hơn (more; than) to express a higher degree and ít hơn (less) for a lower degree.
For example:
nhanh hơn (faster)
đẹp hơn (more beautiful)
quan trọng hơn (more important)
ít đắt hơn (less expensive)
The adjective or adverb itself does not change form.

Nhất

nhất means most or expresses the highest degree.
For example:
nhanh nhất (fastest)
đẹp nhất (most beautiful)
tốt nhất (best)
quan trọng nhất (most important)
In a sentence:
Anh ấy chạy nhanh nhất. (He runs the fastest.)

Adverbs of Place

Vietnamese uses several common expressions to indicate location or direction.
Examples include:
đây (here)
đó (there; that place)
kia (over there)
đâu (where)
ở đây (here)
ở đó (there)
ở đâu (where)
For example:
Tôi ở đây. (I am here.)
Anh ấy đang ở đó. (He is there.)
Bạn sống ở đâu? (Where do you live?)

Đây

đây means here or can refer to something near the speaker.
For example:
Tôi ở đây. (I am here.)
Đến đây! (Come here!)
It can also function as a demonstrative element in structures such as:
Đây là nhà tôi. (This is my house.)

Đó

đó can mean there or refer to something relatively distant from the speaker.
For example:
Anh ấy ở đó. (He is there.)
Đừng đi đến đó. (Do not go there.)
It is also commonly used as a demonstrative:
Nhà đó rất đẹp. (That house is very beautiful.)

Kia

kia generally refers to something farther away and can be translated as over there or that over there.
For example:
Nhìn kia! (Look over there!)
Người kia là ai? (Who is that person over there?)
Its exact interpretation depends on the physical or conversational context.

Đâu

đâu is an important question word meaning where.
For example:
Bạn ở đâu? (Where are you?)
Bạn đi đâu? (Where are you going?)
Nhà ga ở đâu? (Where is the station?)
It usually appears in the position where the requested information would appear rather than automatically moving to the beginning of the sentence.

Adverbs of Certainty

Vietnamese has several words that express certainty, probability, or possibility.
Common examples include:
chắc chắn (certainly; definitely)
chắc (probably; likely)
có lẽ (perhaps; probably)
có thể (possibly; can; may)
For example:
Anh ấy chắc chắn sẽ đến. (He will definitely come.)
Có lẽ trời sẽ mưa. (Perhaps it will rain.)
These expressions allow speakers to show how confident they are about a statement.

Chắc Chắn

chắc chắn means certainly, definitely, or for sure.
For example:
Tôi chắc chắn sẽ đến. (I will definitely come.)
Điều này chắc chắn đúng. (This is definitely correct.)
It expresses a relatively high degree of confidence.

Có Lẽ

có lẽ means perhaps, maybe, or probably.
For example:
Có lẽ anh ấy đang ở nhà. (Perhaps he is at home.)
Có lẽ ngày mai trời mưa. (Maybe it will rain tomorrow.)
It frequently appears at the beginning of a sentence.

Có Thể

có thể can mean possibly, can, or may depending on context.
For example:
Anh ấy có thể đến muộn. (He may arrive late.)
Tôi có thể giúp bạn. (I can help you.)
Its role can therefore be adverbial or modal depending on the sentence.

Adverbs of Sequence

Vietnamese frequently uses adverbial expressions to show the order of events.
Common examples include:
đầu tiên (first; firstly)
sau đó (after that; then)
tiếp theo (next)
cuối cùng (finally)
For example:
Đầu tiên chúng tôi ăn sáng. (First, we eat breakfast.)
Sau đó chúng tôi đi làm. (After that, we go to work.)
Cuối cùng chúng tôi về nhà. (Finally, we go home.)
These expressions are especially useful in explanations, instructions, and narratives.

Đầu Tiên

đầu tiên means first or firstly.
For example:
Đầu tiên, hãy đọc bài này. (First, read this text.)
It often appears at the beginning of a sentence or clause.

Sau Đó

sau đó means after that or then.
For example:
Tôi ăn sáng, sau đó tôi đi làm. (I eat breakfast, then I go to work.)
It connects actions in chronological order.

Tiếp Theo

tiếp theo means next or following that.
For example:
Tiếp theo, chúng ta học từ mới. (Next, we learn new vocabulary.)
It is common in instructions, lessons, and organized explanations.

Cuối Cùng

cuối cùng means finally, eventually, or in the end.
For example:
Cuối cùng chúng tôi đến khách sạn. (Finally, we arrive at the hotel.)
Its exact meaning depends on whether it emphasizes the last step in a sequence or the eventual result of a process.

Adverbs of Addition

Vietnamese has several words meaning also, too, or in addition.
The most common include:
cũng (also; too)
thêm (more; additionally)
nữa (also; more; again)
For example:
Tôi cũng thích cà phê. (I also like coffee.)
Cô ấy cũng nói tiếng Anh. (She also speaks English.)

Cũng

cũng is one of the most common Vietnamese adverbs and normally appears before the verb or adjective.
For example:
Tôi cũng đi. (I am going too.)
Anh ấy cũng mệt. (He is also tired.)
Chúng tôi cũng thích món này. (We also like this dish.)
Its position helps show exactly which part of the sentence is being included.

Nữa

nữa can mean more, again, also, or any longer depending on context.
For example:
một lần nữa (one more time; again)
một cái nữa (one more)
Tôi muốn ăn nữa. (I want to eat more.)
With negation:
Tôi không làm việc ở đó nữa. (I do not work there anymore.)
This is a very common conversational pattern.

Lại

lại often means again or indicates that an action is repeated.
For example:
Nói lại, xin vui lòng. (Please say it again.)
Anh ấy lại đến muộn. (He is late again.)
It can carry additional meanings in different grammatical constructions, so context is important.

Vẫn

vẫn means still or nevertheless and indicates continuation.
For example:
Tôi vẫn sống ở Hà Nội. (I still live in Hanoi.)
Anh ấy vẫn đang ngủ. (He is still sleeping.)
Trời mưa nhưng chúng tôi vẫn đi. (It is raining, but we are still going.)
It often emphasizes that a situation continues despite time or circumstances.

Chưa

chưa commonly means not yet and is also used in questions asking whether something has happened yet.
For example:
Tôi chưa ăn. (I have not eaten yet.)
Anh ấy chưa đến. (He has not arrived yet.)
A very common question is:
Bạn ăn chưa? (Have you eaten yet?)
An affirmative answer can use rồi:
Ăn rồi. (I have eaten already.)
This chưa ... rồi contrast is fundamental in everyday Vietnamese.

Mới

mới can function as an adverb meaning just, only recently, or sometimes only.
For example:
Tôi mới đến. (I have just arrived.)
Anh ấy mới bắt đầu học tiếng Việt. (He has just started learning Vietnamese.)
It can also be an adjective meaning new, so its function depends on position and context.

Vừa

vừa can indicate that an action has just occurred.
For example:
Tôi vừa ăn. (I just ate.)
Cô ấy vừa về nhà. (She has just returned home.)
Vietnamese also uses the structure vừa ... vừa ... to express two simultaneous characteristics or actions:
Cô ấy vừa thông minh vừa thân thiện. (She is both intelligent and friendly.)

Sắp

sắp means soon or indicates that something is about to happen.
For example:
Tôi sắp đi. (I am about to leave.)
Trời sắp mưa. (It is about to rain.)
Chuyến tàu sắp đến. (The train is about to arrive.)
It normally appears before the verb.

Ngay

ngay can mean immediately, right, or exactly depending on context.
For example:
Đi ngay! (Go immediately!)
Tôi sẽ gọi ngay. (I will call right away.)
ngay bây giờ (right now)
It often strengthens the immediacy or precision of another expression.

Ngay Lập Tức

ngay lập tức means immediately or at once.
For example:
Hãy gọi bác sĩ ngay lập tức. (Call the doctor immediately.)
This expression is stronger and more explicit than simple ngay.

Chỉ

chỉ commonly means only or just.
For example:
Tôi chỉ có một câu hỏi. (I only have one question.)
Anh ấy chỉ uống nước. (He only drinks water.)
Chỉ năm phút thôi. (Only five minutes.)
Its position determines what part of the sentence is being limited.

Thôi

thôi is a very common conversational particle and adverbial element that can mean only, just, that's all, or indicate stopping.
For example:
Một cà phê thôi. (Just one coffee.)
Thế thôi. (That's all.)
Đừng nói nữa, thôi! (Stop talking, enough!)
Its exact meaning depends heavily on tone and context.

Adverbs with Negation

Vietnamese commonly places không (not) before verbs and adjectives.
For example:
Tôi không biết. (I do not know.)
Cô ấy không vui. (She is not happy.)
Anh ấy không thường xuyên đi du lịch. (He does not travel frequently.)
For completed or not-yet actions, chưa is often more appropriate:
Tôi chưa biết. (I do not know yet.)
Chúng tôi chưa ăn. (We have not eaten yet.)

Adverbs and Questions

Vietnamese question words often remain in the position where the answer would normally appear.
Examples include:
khi nào (when)
ở đâu (where)
như thế nào (how)
bao lâu (how long)
bao giờ (when; ever)
For example:
Bạn đi khi nào? (When are you going?)
Bạn sống ở đâu? (Where do you live?)
Bạn học tiếng Việt như thế nào? (How do you learn Vietnamese?)

Adverb Placement

Vietnamese adverb placement depends largely on meaning.
Time expressions often appear at the beginning:
Ngày mai tôi đi làm. (Tomorrow I go to work.)
Frequency adverbs normally appear before the verb:
Tôi thường đi bộ. (I usually walk.)
Manner adverbs frequently follow the verb:
Cô ấy nói chậm. (She speaks slowly.)
Degree adverbs usually precede adjectives:
rất đẹp (very beautiful)
Certain degree expressions can follow adjectives:
Đẹp quá! (So beautiful!)
Learning these common patterns is more useful than trying to apply one fixed rule to every adverb.

Several Adverbs in One Sentence

Vietnamese sentences can contain several adverbial elements at the same time.
For example:
Hôm nay tôi vẫn đang làm việc ở nhà. (Today I am still working at home.)
Here:
hôm nay establishes time,
vẫn expresses continuation,
đang marks an ongoing action,
and ở nhà gives location.
Another example:
Ngày mai tôi sẽ đi làm sớm. (Tomorrow I will go to work early.)
Vietnamese generally arranges these elements according to their function and emphasis.

Time Before Place

A common neutral ordering pattern places time before the main clause and location later:
Hôm nay tôi làm việc ở nhà. (Today I work at home.)
Ngày mai chúng tôi ăn tối ở nhà hàng. (Tomorrow we will have dinner at a restaurant.)
However, Vietnamese word order is flexible enough to move certain elements forward for emphasis.

Common Adverb Combinations

Vietnamese frequently combines several adverbs naturally:
vẫn còn (still remaining; still)
đã từng (have ever; used to have experienced)
chưa bao giờ (never yet; have never)
sắp sửa (about to)
ngay bây giờ (right now)
rất thường xuyên (very frequently)
For example:
Tôi chưa bao giờ đến Việt Nam. (I have never been to Vietnam.)
Cô ấy vẫn còn ở nhà. (She is still at home.)
Chúng tôi sắp sửa đi. (We are about to leave.)
These combinations are often best learned as complete patterns.

Đã Từng

đã từng is commonly used when talking about past experience.
For example:
Tôi đã từng sống ở Việt Nam. (I have lived in Vietnam before.)
Bạn đã từng ăn phở chưa? (Have you ever eaten phở?)
The word từng adds the idea of having experienced something at some point.

Chưa Bao Giờ

chưa bao giờ means have never or never yet.
For example:
Tôi chưa bao giờ đến Huế. (I have never been to Hue.)
It combines naturally with questions about life experience.

Still and Already

The contrast between vẫn (still) and rồi (already; now) is common:
Tôi vẫn đang làm việc. (I am still working.)
Tôi làm xong rồi. (I have finished already.)
These expressions help speakers describe whether a situation continues or has changed.

Yet and Already

Vietnamese often contrasts chưa (not yet) with rồi (already).
For example:
Bạn ăn chưa? (Have you eaten yet?)
Tôi chưa ăn. (I have not eaten yet.)
Tôi ăn rồi. (I have already eaten.)
This pattern appears constantly in everyday conversation.

Very and Too

Learners should distinguish rất (very) from quá (too; extremely).
Compare:
rất đắt (very expensive)
quá đắt (too expensive)
However, conversational quá after an adjective may simply express strong admiration or emotion:
Đẹp quá! (So beautiful!)
Its interpretation therefore depends on context and word order.

Adverb Meaning Depends on Context

Many Vietnamese adverbs have several possible English translations.
For example, rồi may mean already, then, or indicate a completed change. lại can mean again but has additional grammatical uses. mới can mean just, only, or function as the adjective new.
Learners should therefore avoid memorizing every Vietnamese adverb with only one English equivalent.

Learning Adverbs in Phrases

Adverbs are easiest to learn as parts of complete expressions.
Instead of memorizing only thường (usually), learn:
Tôi thường đi bộ. (I usually walk.)
Instead of memorizing only chưa (not yet), learn:
Tôi chưa biết. (I do not know yet.)
Instead of memorizing only rồi (already), learn:
Tôi hiểu rồi. (I understand now.)
This approach makes their natural sentence position much easier to remember.

Common Vietnamese Adverbs

Useful everyday forms include:
bây giờ (now)
hôm nay (today)
hôm qua (yesterday)
ngày mai (tomorrow)
thường (usually)
luôn luôn (always)
đôi khi (sometimes)
hiếm khi (rarely)
không bao giờ (never)
rất (very)
khá (quite)
hơi (slightly)
quá (too; extremely)
nhanh (quickly)
chậm (slowly)
cũng (also)
lại (again)
vẫn (still)
chưa (not yet)
rồi (already)
sắp (soon; about to)
ngay (immediately; right)
có lẽ (perhaps)
chắc chắn (definitely)
đầu tiên (first)
sau đó (then)
cuối cùng (finally)

Present Tense in Vietnamese

Vietnamese verbs are relatively simple because they do not change form according to person, number, or grammatical tense. The same verb can be used with tôi (I), bạn (you), anh ấy (he), or họ (they) without changing its ending. Present-time meaning is usually understood from context, time expressions, and particles.

Basic Verb Structure

The simplest Vietnamese sentence often follows the pattern:
subject + verb + object
For example:
Tôi uống cà phê. (I drink coffee.)
Cô ấy đọc sách. (She reads books.)
Họ học tiếng Việt. (They study Vietnamese.)
The verb remains unchanged regardless of the subject.
Compare:
Tôi làm việc. (I work.)
Anh ấy làm việc. (He works.)
Chúng tôi làm việc. (We work.)
The verb làm việc (to work) has exactly the same form in every sentence.

No Verb Conjugation

Vietnamese verbs do not have endings corresponding to different persons.
For example, ăn means to eat:
Tôi ăn. (I eat.)
Bạn ăn. (You eat.)
Cô ấy ăn. (She eats.)
Họ ăn. (They eat.)
There is no separate form equivalent to eats. The subject tells you who performs the action.

Present-Time Meaning

A bare Vietnamese verb can describe an action happening in the present, a habit, or a general fact.
For example:
Tôi sống ở Hà Nội. (I live in Hanoi.)
Anh ấy làm việc ở bệnh viện. (He works at a hospital.)
Tôi thích âm nhạc. (I like music.)
Cô ấy nói tiếng Việt. (She speaks Vietnamese.)
No special present-tense marker is required.

Đang: Actions Happening Now

When the speaker wants to emphasize that an action is happening right now or is currently in progress, Vietnamese commonly uses đang (currently; in the process of).
The structure is:
subject + đang + verb
For example:
Tôi đang ăn. (I am eating.)
Cô ấy đang ngủ. (She is sleeping.)
Anh ấy đang làm việc. (He is working.)
Chúng tôi đang học tiếng Việt. (We are studying Vietnamese.)
đang is similar in function to the progressive idea in I am working or she is reading.

Đang Is Not Always Necessary

Vietnamese does not require đang whenever an action happens at the present moment. If the context already makes the timing obvious, the simple verb may be enough.
For example:
Bạn làm gì? (What are you doing?; What do you do?)
Depending on context, this can refer either to the current activity or to someone's occupation or usual activity.
To make the progressive meaning explicit:
Bạn đang làm gì? (What are you doing right now?)

Present Habits

Habitual actions are usually expressed with the basic verb, often together with frequency adverbs.
For example:
Tôi uống cà phê mỗi sáng. (I drink coffee every morning.)
Anh ấy thường đi bộ đến trường. (He usually walks to school.)
Cô ấy luôn đến đúng giờ. (She always arrives on time.)
Common frequency expressions include:
thường (usually; often)
luôn (always)
đôi khi (sometimes)
thỉnh thoảng (occasionally)
hiếm khi (rarely)
mỗi ngày (every day)
These words help clarify that an action happens regularly.

Present States

Vietnamese also uses simple verbs and adjectives to describe present states.
For example:
Tôi biết. (I know.)
Tôi hiểu. (I understand.)
Cô ấy thích cà phê. (She likes coffee.)
Anh ấy muốn đi. (He wants to go.)
Verbs such as biết (to know), hiểu (to understand), thích (to like), and muốn (to want) normally do not need đang when describing an ordinary state.

Common Vietnamese Verbs

Useful everyday verbs include:
ăn (to eat)
uống (to drink)
đi (to go)
đến (to come; to arrive)
làm (to do; to make)
làm việc (to work)
học (to study; to learn)
đọc (to read)
viết (to write)
nói (to speak; to say)
nghe (to listen; to hear)
xem (to watch; to look at)
sống (to live)
biết (to know)
hiểu (to understand)
thích (to like)
muốn (to want)
cần (to need)
For example:
Tôi học tiếng Việt. (I study Vietnamese.)
Cô ấy đọc báo. (She reads the newspaper.)
Anh ấy muốn uống nước. (He wants to drink water.)

Verb + Verb

Vietnamese can place verbs together without changing their form.
For example:
muốn ăn (to want to eat)
cần làm việc (to need to work)
thích đọc sách (to like reading books)
đi mua sắm (to go shopping)
In a sentence:
Tôi muốn học tiếng Việt. (I want to learn Vietnamese.)
Cô ấy thích nghe nhạc. (She likes listening to music.)
There is generally no equivalent of an infinitive ending such as to built into the verb itself.

Negating Present-Tense Verbs

Present actions and states are usually negated with không (not).
The basic pattern is:
subject + không + verb
For example:
Tôi không biết. (I do not know.)
Anh ấy không uống cà phê. (He does not drink coffee.)
Cô ấy không sống ở đây. (She does not live here.)
Chúng tôi không hiểu. (We do not understand.)
The verb itself remains unchanged.

Asking Yes-or-No Questions

A common way to form a yes-or-no question is to add không at the end of the sentence.
For example:
Bạn nói tiếng Việt không? (Do you speak Vietnamese?)
Anh ấy làm việc ở đây không? (Does he work here?)
Bạn thích cà phê không? (Do you like coffee?)
Another common structure is:
có + verb + không?
For example:
Bạn có hiểu không? (Do you understand?)
Cô ấy có làm việc ở đây không? (Does she work here?)
Both patterns are common in everyday Vietnamese.

Answering Questions

Simple affirmative answers often use có (yes; do) when appropriate:
Bạn có nói tiếng Việt không? (Do you speak Vietnamese?)
Có. (Yes.)
A negative answer uses không:
Không. (No.)
You can also repeat the verb:
Có, tôi nói tiếng Việt. (Yes, I speak Vietnamese.)
Không, tôi không nói tiếng Việt. (No, I do not speak Vietnamese.)

Questions with Question Words

Vietnamese normally keeps question words in the position where the answer would appear.
For example:
Bạn làm gì? (What do you do?; What are you doing?)
Bạn sống ở đâu? (Where do you live?)
Bạn học tiếng Việt ở đâu? (Where do you study Vietnamese?)
Bạn đi làm khi nào? (When do you go to work?)
Common question words include:
gì (what)
ai (who)
ở đâu (where)
khi nào (when)
tại sao (why)
như thế nào (how)

Present Time Expressions

Time expressions can make the present meaning clearer.
Common examples include:
bây giờ (now)
hôm nay (today)
lúc này (at this moment)
mỗi ngày (every day)
mỗi sáng (every morning)
For example:
Bây giờ tôi đang làm việc. (I am working now.)
Hôm nay tôi làm việc ở nhà. (Today I am working at home.)
Mỗi ngày tôi học tiếng Việt. (Every day I study Vietnamese.)

Present Actions and Word Order

Time expressions often appear at the beginning of a sentence:
Hôm nay tôi làm việc ở nhà. (Today I work at home.)
Frequency words normally appear before the main verb:
Tôi thường đọc sách. (I usually read books.)
đang also appears before the verb:
Tôi đang đọc sách. (I am reading a book.)
Several elements can occur together:
Hôm nay tôi đang làm việc ở nhà. (Today I am working at home.)

Là and Present-Tense Sentences

là means to be and is commonly used when identifying or defining a noun.
For example:
Tôi là giáo viên. (I am a teacher.)
Anh ấy là bác sĩ. (He is a doctor.)
Hà Nội là thủ đô của Việt Nam. (Hanoi is the capital of Vietnam.)
However, là is normally not used directly before ordinary adjectives.
Vietnamese says:
Cô ấy đẹp. (She is beautiful.)
Trời nóng. (It is hot.)
not a structure equivalent to She is beautiful with là inserted before the adjective.

Có

có is another extremely important verb. It can mean to have or there is/there are, depending on the structure.
For possession:
Tôi có một chiếc xe. (I have a car.)
Cô ấy có hai con. (She has two children.)
For existence:
Có một nhà hàng gần đây. (There is a restaurant nearby.)
The negative is:
không có (do not have; there is not)
Tôi không có xe. (I do not have a car.)

Present Progressive with Vẫn and Đang

Vietnamese can combine vẫn (still) with đang to show that an action continues.
For example:
Tôi vẫn đang làm việc. (I am still working.)
Cô ấy vẫn đang ngủ. (She is still sleeping.)
This combination is common when emphasizing continuation.

Key Point

Vietnamese present-tense verbs are simple because verbs do not conjugate. A form such as học (to study) remains the same in Tôi học (I study), Cô ấy học (She studies), and Họ học (They study). The basic verb can express present habits, facts, and states, while đang is used when the speaker wants to emphasize an action currently in progress. Negation is normally formed with không (not), and time expressions such as bây giờ (now), hôm nay (today), and mỗi ngày (every day) help clarify the meaning without changing the verb itself.

Past Tense in Vietnamese

Vietnamese verbs do not change form to express the past. Instead, past meaning is usually shown through context, time expressions, and particles such as đã (already; past/completed action). The verb itself remains unchanged.

Basic Past Structure

A common pattern is:
subject + đã + verb
For example:
Tôi đã ăn. (I ate; I have eaten.)
Cô ấy đã về nhà. (She went home; she has gone home.)
Chúng tôi đã gặp nhau. (We met; we have met.)
The word đã normally appears before the main verb.

No Past-Tense Conjugation

Vietnamese verbs do not receive special past endings.
Compare:
Tôi học tiếng Việt. (I study Vietnamese.)
Hôm qua tôi học tiếng Việt. (Yesterday I studied Vietnamese.)
The verb học (to study; to learn) remains exactly the same.
This also applies to every grammatical person:
Tôi đã làm việc. (I worked.)
Anh ấy đã làm việc. (He worked.)
Họ đã làm việc. (They worked.)

Đã

đã is the most common marker associated with completed or past actions.
For example:
Tôi đã đọc cuốn sách này. (I read/have read this book.)
Anh ấy đã đến Hà Nội. (He went/has been to Hanoi.)
Cô ấy đã gọi cho tôi. (She called me.)
However, đã is not compulsory every time an action happened in the past.

Past Meaning Without Đã

If the sentence already contains a clear past-time expression, Vietnamese can omit đã.
For example:
Hôm qua tôi đi làm. (Yesterday I went to work.)
Tuần trước chúng tôi đến Huế. (Last week we went to Hue.)
Năm ngoái cô ấy sống ở Việt Nam. (Last year she lived in Vietnam.)
The expressions hôm qua (yesterday), tuần trước (last week), and năm ngoái (last year) already establish the past.

Common Past-Time Expressions

Useful expressions include:
hôm qua (yesterday)
hôm kia (the day before yesterday)
tuần trước (last week)
tháng trước (last month)
năm ngoái (last year)
trước đây (previously; in the past)
lúc đó (at that time)
For example:
Tháng trước tôi đi Đà Nẵng. (Last month I went to Da Nang.)
Trước đây tôi sống ở Hà Nội. (I used to live in Hanoi.)

Rồi

rồi often indicates that an action has already been completed or that a new state has been reached.
It normally appears after the verb or phrase:
Tôi ăn rồi. (I have eaten already.)
Anh ấy về rồi. (He has gone home already.)
Cô ấy đến rồi. (She has arrived.)
The exact English translation depends on context.

Đã and Rồi Together

Vietnamese can use both đã and rồi when emphasizing completion:
Tôi đã ăn rồi. (I have already eaten.)
Anh ấy đã về rồi. (He has already gone home.)
Using both is common, but not necessary in every past sentence.

Chưa

chưa means not yet and is commonly used when an expected action has not happened.
For example:
Tôi chưa ăn. (I have not eaten yet.)
Cô ấy chưa đến. (She has not arrived yet.)
Chúng tôi chưa quyết định. (We have not decided yet.)
A very common question is:
Bạn ăn chưa? (Have you eaten yet?)
A possible answer is:
Ăn rồi. (Yes, I have eaten already.)

Negative Past Actions

Vietnamese commonly uses không (not) when simply stating that a past action did not happen.
For example:
Hôm qua tôi không đi làm. (Yesterday I did not go to work.)
Anh ấy không gọi cho tôi. (He did not call me.)
Chúng tôi không gặp cô ấy. (We did not meet her.)
Use chưa instead when the meaning is not yet.
Compare:
Tôi không ăn. (I did not eat; I do not eat, depending on context.)
Tôi chưa ăn. (I have not eaten yet.)

Just Happened: Vừa

vừa is commonly used for an action that happened very recently.
For example:
Tôi vừa ăn. (I just ate.)
Cô ấy vừa về nhà. (She has just returned home.)
Anh ấy vừa gọi cho tôi. (He just called me.)
It normally appears before the verb.

Mới

mới can also indicate that something happened recently.
For example:
Tôi mới đến. (I just arrived.)
Anh ấy mới bắt đầu học tiếng Việt. (He has just started learning Vietnamese.)
The precise difference between vừa and mới depends on context and emphasis, and both are very common in conversation.

Past Experience with Từng

từng is used when talking about an experience that happened at least once in the past.
For example:
Tôi từng sống ở Việt Nam. (I once lived in Vietnam; I have lived in Vietnam before.)
Cô ấy từng làm việc ở đây. (She used to work here; she has worked here before.)
It often appears as đã từng:
Tôi đã từng đến Huế. (I have been to Hue before.)

Asking About Past Experience

A common pattern is:
đã từng + verb + chưa?
For example:
Bạn đã từng đến Việt Nam chưa? (Have you ever been to Vietnam?)
Bạn đã từng ăn phở chưa? (Have you ever eaten phở?)
Possible answers include:
Rồi. (Yes; already.)
Chưa. (Not yet; no.)

Used to

Past habits or former situations can often be expressed with trước đây (previously; formerly) or từng (once; used to).
For example:
Trước đây tôi sống ở Hà Nội. (I used to live in Hanoi.)
Anh ấy từng làm giáo viên. (He used to be a teacher.)
Context usually makes it clear that the situation no longer continues.

Sequence of Past Events

Vietnamese often uses time expressions and connecting words to show the order of past events.
For example:
Hôm qua tôi ăn sáng, sau đó tôi đi làm. (Yesterday I ate breakfast, then I went to work.)
Đầu tiên chúng tôi đến khách sạn, sau đó chúng tôi đi ăn. (First we arrived at the hotel, then we went to eat.)
Useful sequencing expressions include:
đầu tiên (first)
sau đó (then; after that)
cuối cùng (finally)

Past Questions

Past questions can use đã when the speaker wants to ask whether an action has happened.
For example:
Bạn đã ăn chưa? (Have you eaten yet?)
Anh ấy đã về chưa? (Has he gone home yet?)
Bạn đã đọc sách này chưa? (Have you read this book yet?)
The pattern đã ... chưa? is extremely common.

Time Expressions and Word Order

Past-time expressions often appear at the beginning of the sentence:
Hôm qua tôi đã gặp cô ấy. (Yesterday I met her.)
Tuần trước chúng tôi đi Hà Nội. (Last week we went to Hanoi.)
They can also appear later:
Tôi gặp cô ấy hôm qua. (I met her yesterday.)
Vietnamese word order is flexible when the meaning remains clear.

Past States

Past states can also be expressed without changing the adjective or verb.
For example:
Hôm qua tôi rất mệt. (Yesterday I was very tired.)
Lúc đó cô ấy còn trẻ. (At that time she was still young.)
Trước đây nhà này rất nhỏ. (This house used to be very small.)
No separate past form of to be is required before ordinary adjectives.

Common Past Verb Examples

đã ăn (ate; have eaten)
đã đi (went; have gone)
đã đến (came; arrived)
đã làm (did; made)
đã học (studied; learned)
đã nói (said; spoke)
đã xem (watched; saw)
đã gặp (met)
đã sống (lived)
đã biết (knew; found out)
The original verb stays unchanged in every case.

Key Point

Vietnamese does not have a separate conjugated past tense. Verbs such as ăn (to eat), đi (to go), and học (to study) keep the same form in the present and past. Past meaning is shown mainly through context, time expressions such as hôm qua (yesterday) and năm ngoái (last year), and particles such as đã (past/completed action), rồi (already), chưa (not yet), vừa (just), and từng (once; previously experienced). Learning these markers is more important than memorizing verb forms because Vietnamese verbs themselves never conjugate for tense.

Future Tense in Vietnamese

Vietnamese verbs do not change form to express the future. Future meaning is usually shown through context, time expressions, and words such as sẽ (will; future marker). The verb itself remains unchanged.

Basic Future Structure

A common pattern is:
subject + sẽ + verb
For example:
Tôi sẽ đi. (I will go.)
Cô ấy sẽ gọi cho bạn. (She will call you.)
Chúng tôi sẽ học tiếng Việt. (We will study Vietnamese.)
The word sẽ normally appears before the main verb.

No Future-Tense Conjugation

Vietnamese verbs have no special future endings.
Compare:
Tôi làm việc. (I work.)
Ngày mai tôi sẽ làm việc. (Tomorrow I will work.)
The verb làm việc (to work) does not change.
The same is true with different subjects:
Tôi sẽ đi. (I will go.)
Anh ấy sẽ đi. (He will go.)
Họ sẽ đi. (They will go.)

Future Meaning Without Sẽ

When a clear future-time expression is already present, sẽ may be omitted.
For example:
Ngày mai tôi đi Hà Nội. (Tomorrow I am going to Hanoi.)
Tuần sau chúng tôi gặp nhau. (Next week we will meet.)
Tháng tới cô ấy bắt đầu công việc mới. (Next month she will start a new job.)
The time expression already makes the future meaning clear.

Common Future-Time Expressions

Useful expressions include:
ngày mai (tomorrow)
ngày kia (the day after tomorrow)
tuần sau (next week)
tháng sau (next month)
năm sau (next year)
sắp tới (in the near future; upcoming)
sau này (later; in the future)
For example:
Năm sau tôi sẽ đến Việt Nam. (Next year I will go to Vietnam.)
Tuần sau chúng tôi sẽ bắt đầu khóa học. (Next week we will begin the course.)

Sẽ

sẽ is the most common general marker of future meaning.
For example:
Tôi sẽ gọi cho bạn. (I will call you.)
Trời sẽ mưa. (It will rain.)
Anh ấy sẽ đến lúc tám giờ. (He will arrive at eight o'clock.)
It can express predictions, plans, promises, and future events.

Sắp

sắp indicates that something is going to happen soon or is about to happen.
For example:
Tôi sắp đi. (I am about to leave.)
Trời sắp mưa. (It is about to rain.)
Xe buýt sắp đến. (The bus is about to arrive.)
It normally appears before the verb.

Sắp Sửa

sắp sửa also means to be about to or to be preparing to.
For example:
Chúng tôi sắp sửa khởi hành. (We are about to depart.)
Cô ấy sắp sửa bắt đầu công việc mới. (She is about to start a new job.)
This form often emphasizes that an event is approaching very soon.

Going to Do Something

Vietnamese can express a planned future simply through context or with words such as sẽ and sắp.
For example:
Tối nay tôi đi ăn với bạn. (Tonight I am going to eat with a friend.)
Tôi sẽ mua một chiếc xe mới. (I will buy a new car.)
Tôi sắp mua nhà. (I am about to buy a house.)
There is no single Vietnamese construction that must always correspond to English going to.

Future Plans

Planned actions often combine a future-time expression with a simple verb.
For example:
Cuối tuần này chúng tôi đi biển. (This weekend we are going to the beach.)
Ngày mai tôi gặp bác sĩ. (Tomorrow I am seeing the doctor.)
Tháng sau cô ấy chuyển đến Hà Nội. (Next month she is moving to Hanoi.)
Because the future time is explicit, sẽ is optional in many such sentences.

Predictions

sẽ is particularly common when making predictions.
For example:
Ngày mai trời sẽ nóng. (Tomorrow it will be hot.)
Giá sẽ tăng. (Prices will increase.)
Việc này sẽ khó. (This will be difficult.)
The future marker comes before the verb or adjective expressing the predicted situation.

Promises and Decisions

sẽ can also express a promise, decision, or intention.
For example:
Tôi sẽ giúp bạn. (I will help you.)
Tôi sẽ gọi lại. (I will call back.)
Chúng tôi sẽ không quên. (We will not forget.)
Context determines whether the sentence describes a prediction, plan, or promise.

Negative Future

Future actions are normally negated by placing không (not) before the main verb.
For example:
Tôi sẽ không đi. (I will not go.)
Anh ấy sẽ không đến. (He will not come.)
Chúng tôi sẽ không làm việc ngày mai. (We will not work tomorrow.)
The common order is:
subject + sẽ + không + verb

Chưa in Future Contexts

chưa (not yet) can describe something that has not happened but is expected to happen later.
For example:
Tôi chưa quyết định. (I have not decided yet.)
Chúng tôi chưa biết khi nào sẽ đi. (We do not yet know when we will go.)
The future meaning normally comes from the surrounding context rather than from chưa itself.

Future Questions

Questions about the future often use sẽ:
Bạn sẽ đi đâu? (Where will you go?)
Khi nào bạn sẽ đến? (When will you arrive?)
Anh ấy sẽ làm gì? (What will he do?)
However, sẽ may be omitted if another expression already clearly indicates future time:
Ngày mai bạn làm gì? (What are you doing tomorrow?)

Yes-or-No Future Questions

A common pattern is:
subject + có + verb + không?
or a sentence containing sẽ followed by không at the end.
For example:
Ngày mai bạn có đi làm không? (Are you going to work tomorrow?)
Bạn sẽ đến không? (Will you come?)
A simple answer may be:
Có. (Yes.)
Không. (No.)

When

The question expression khi nào means when.
For example:
Khi nào bạn sẽ về? (When will you return?)
Bạn sẽ đi Việt Nam khi nào? (When will you go to Vietnam?)
Vietnamese question expressions often remain in the natural position of the information being requested.

Future with Muốn

muốn (to want) can express a future intention or desire.
For example:
Tôi muốn học tiếng Việt. (I want to learn Vietnamese.)
Cô ấy muốn sống ở Hà Nội. (She wants to live in Hanoi.)
Chúng tôi muốn đi du lịch năm sau. (We want to travel next year.)
The verb following muốn remains unchanged.

Future with Định

định is commonly used to express an intention or plan and can often be translated as intend to or plan to.
For example:
Tôi định đi Hà Nội. (I intend to go to Hanoi.)
Bạn định làm gì cuối tuần này? (What are you planning to do this weekend?)
Cô ấy định học tiếng Việt. (She plans to study Vietnamese.)
This is especially useful when discussing personal plans.

Future with Dự Định

dự định means to plan; to intend and can also function as a noun meaning plan.
For example:
Tôi dự định đi Việt Nam năm sau. (I plan to go to Vietnam next year.)
Chúng tôi dự định mua nhà. (We plan to buy a house.)
It often sounds more explicit than simple định.

Future with Hy Vọng

hy vọng means to hope.
For example:
Tôi hy vọng sẽ gặp bạn sớm. (I hope to see you soon.)
Chúng tôi hy vọng thời tiết sẽ tốt. (We hope the weather will be good.)
The combination hy vọng + sẽ is very common when expressing hopes about future events.

Future Possibility

Vietnamese often uses có thể (can; may; possibly) to express future possibility.
For example:
Ngày mai trời có thể mưa. (It may rain tomorrow.)
Anh ấy có thể sẽ đến muộn. (He may arrive late.)
Chúng tôi có thể đi vào tuần sau. (We may go next week.)
The combination có thể sẽ explicitly combines possibility with future meaning.

Future Probability

Words such as chắc (probably) and có lẽ (perhaps; probably) can also describe uncertain future events.
For example:
Anh ấy chắc sẽ đến. (He will probably come.)
Có lẽ ngày mai trời sẽ mưa. (Perhaps it will rain tomorrow.)
These expressions show the speaker's degree of certainty.

Verb Combinations

Vietnamese future expressions can contain several verbs without changing their forms.
For example:
Tôi sẽ đi mua thức ăn. (I will go buy food.)
Cô ấy sẽ bắt đầu học tiếng Việt. (She will start learning Vietnamese.)
Chúng tôi sẽ cố gắng giúp bạn. (We will try to help you.)
Only the surrounding markers and context show the future meaning.

Là in Future Sentences

là (to be) can appear with sẽ when identifying a future role or state involving a noun.
For example:
Anh ấy sẽ là bác sĩ. (He will be a doctor.)
Đây sẽ là một ngày quan trọng. (This will be an important day.)
With ordinary adjectives, là is normally unnecessary:
Ngày mai trời sẽ lạnh. (Tomorrow it will be cold.)

Có in Future Sentences

có (to have; there is/are) can also appear in future constructions.
For example:
Tôi sẽ có nhiều thời gian hơn. (I will have more time.)
Ngày mai sẽ có một cuộc họp. (There will be a meeting tomorrow.)
Sẽ có nhiều người tham gia. (There will be many participants.)

Future Sequence

Future events can be connected with sequence expressions such as:
đầu tiên (first)
sau đó (then; after that)
tiếp theo (next)
cuối cùng (finally)
For example:
Ngày mai chúng tôi sẽ ăn sáng, sau đó sẽ đi tham quan. (Tomorrow we will have breakfast and then go sightseeing.)

Before and After

Future events are frequently organized with trước khi (before) and sau khi (after).
For example:
Tôi sẽ gọi cho bạn trước khi đi. (I will call you before leaving.)
Sau khi ăn, chúng tôi sẽ về nhà. (After eating, we will go home.)
The verbs following these expressions remain unchanged.

If

Future conditions commonly use nếu (if).
For example:
Nếu trời mưa, tôi sẽ ở nhà. (If it rains, I will stay home.)
Nếu có thời gian, chúng tôi sẽ đi Huế. (If we have time, we will go to Hue.)
Vietnamese does not require a special future form inside the nếu clause.

Common Future Verb Examples

sẽ đi (will go)
sẽ đến (will come; will arrive)
sẽ làm (will do; will make)
sẽ học (will study)
sẽ nói (will speak; will say)
sẽ gặp (will meet)
sẽ mua (will buy)
sẽ sống (will live)
sắp đi (about to leave)
định đi (intend to go)
The main verb remains unchanged in every expression.

Key Point

Vietnamese has no conjugated future tense. Verbs such as đi (to go), làm (to do; to work), and học (to study) keep the same form regardless of when the action happens. Future meaning is mainly expressed with sẽ (will), future-time phrases such as ngày mai (tomorrow) and tuần sau (next week), or expressions of intention and immediacy such as định (intend to) and sắp (about to). In many sentences, a clear time expression is enough to indicate the future without any additional tense marker.

Imperatives in Vietnamese

Vietnamese verbs do not change form to create the imperative. Commands, requests, instructions, and suggestions are expressed through the basic verb together with particles such as hãy (please; do), đừng (do not), nhé (okay; please), and đi (go ahead; do it). Tone of voice and context are also very important.

Basic Imperative Structure

The simplest command can consist of the verb alone:
Đi! (Go!)
Ngồi! (Sit!)
Đợi! (Wait!)
Nghe! (Listen!)
Because a bare verb can sound direct or strong, Vietnamese often adds particles or polite expressions to make commands more natural.

Hãy

hãy is placed before a verb to introduce a command, instruction, encouragement, or recommendation.
The basic structure is:
hãy + verb
For example:
Hãy ngồi. (Sit down.)
Hãy nghe kỹ. (Listen carefully.)
Hãy đọc bài này. (Read this text.)
Hãy cố gắng. (Try your best.)
hãy is especially common in instructions, written language, formal advice, and educational contexts.

Negative Commands with Đừng

The most common way to tell someone not to do something is:
đừng + verb
For example:
Đừng đi! (Don't go!)
Đừng nói! (Don't speak!)
Đừng lo. (Don't worry.)
Đừng quên. (Don't forget.)
The verb itself does not change.

Đừng ... Nữa

To tell someone to stop doing something, Vietnamese often uses đừng ... nữa (don't ... anymore).
For example:
Đừng nói nữa. (Don't talk anymore; stop talking.)
Đừng khóc nữa. (Don't cry anymore.)
Đừng làm việc nữa. (Stop working.)
The word nữa emphasizes that the action should not continue.

Chớ

chớ also means do not and can introduce a negative command.
For example:
Chớ lo. (Do not worry.)
Chớ quên. (Do not forget.)
It is less common in ordinary conversation than đừng and may sound literary, formal, or proverbial.

Imperatives with Đi

Sentence-final đi is extremely common in spoken Vietnamese. It can encourage someone to perform an action and often makes the command sound more conversational.
For example:
Ăn đi! (Eat!; Go ahead and eat!)
Ngồi đi! (Sit down!)
Nói đi! (Go ahead, say it!)
Thử đi! (Try it!)
The exact tone can range from friendly encouragement to a stronger command depending on the situation.

Imperatives with Nhé

nhé is a very common particle used to soften requests, instructions, and suggestions.
For example:
Đợi tôi nhé. (Wait for me, okay?)
Gọi cho tôi nhé. (Call me, okay?)
Nhớ nhé. (Remember, okay?)
Đi cẩn thận nhé. (Take care; travel safely.)
It gives the sentence a friendlier and less forceful tone.

Please: Xin, Làm Ơn, and Vui Lòng

Vietnamese has several ways to make requests polite.
xin (please; respectfully request)
làm ơn (please; do me a favor)
vui lòng (please; kindly)
Examples:
Xin ngồi. (Please sit.)
Làm ơn giúp tôi. (Please help me.)
Vui lòng chờ một chút. (Please wait a moment.)
Vui lòng is especially common in signs, announcements, customer service, and formal instructions.

Asking Someone to Do Something

A polite request can also use có thể (can; be able to).
For example:
Bạn có thể giúp tôi không? (Can you help me?)
Anh có thể nói chậm hơn không? (Can you speak more slowly?)
Cô có thể viết lại không? (Can you write it again?)
These question forms are often more polite than a direct imperative.

Let's with Nào

nào can be used to encourage a group to begin an action, similar to come on or let's.
For example:
Đi nào! (Let's go!)
Bắt đầu nào! (Let's begin!)
Ăn nào! (Let's eat!)
It is common in friendly and conversational situations.

Chúng Ta and Let's

Vietnamese can also use chúng ta (we, including the listener) to make suggestions involving both speaker and listener.
For example:
Chúng ta đi thôi. (Let's go.)
Chúng ta bắt đầu nhé. (Let's begin, okay?)
Chúng ta ăn ở đây nhé. (Let's eat here.)
This makes the inclusive meaning explicit.

Thôi

thôi can mean that's enough, stop, or contribute to expressions meaning let's go ahead or that's all.
For example:
Đi thôi! (Let's go!)
Dừng lại thôi. (Let's stop.)
Thôi! (Stop!; Enough!)
Its meaning depends strongly on context and intonation.

Commands with Directional Verbs

Vietnamese often uses directional words in commands:
vào (in)
ra (out)
lên (up)
xuống (down)
lại (back; again)
For example:
Đi vào! (Go inside!)
Ra ngoài! (Go outside!)
Đứng lên! (Stand up!)
Ngồi xuống! (Sit down!)
Quay lại! (Come/go back!)
These expressions are extremely common in everyday speech.

Common Classroom Commands

Useful instructional commands include:
Nghe. (Listen.)
Đọc. (Read.)
Viết. (Write.)
Nói. (Speak.)
Lặp lại. (Repeat.)
Trả lời câu hỏi. (Answer the question.)
Mở sách. (Open the book.)
Đóng sách. (Close the book.)
Adding hãy or vui lòng can make these instructions more explicit or polite.

Useful Commands for Learners

Some particularly useful expressions are:
Xin nói chậm. (Please speak slowly.)
Xin nói lại. (Please say it again.)
Làm ơn giúp tôi. (Please help me.)
Đợi một chút. (Wait a moment.)
Nghe kỹ nhé. (Listen carefully, okay?)
Đừng nói nhanh quá. (Don't speak too quickly.)

Pronouns in Commands

Vietnamese often omits the subject in commands because it is already clear who is being addressed.
For example:
Ngồi xuống. (Sit down.)
instead of explicitly saying you sit down.
However, pronouns or kinship terms can be added when useful:
Anh ngồi đi. (Sit down, addressed to an older male.)
Em nghe nhé. (Listen, okay?, addressed to a younger person.)
The choice of pronoun also affects the politeness and social tone of the command.

Strong and Soft Commands

Small particles can significantly change how an imperative sounds.
Compare:
Đi! (Go!) — direct
Đi đi! (Go on!; Go!)
Đi nhé. (Go, okay?) — softer
Đi thôi. (Let's go.)
Xin đi theo tôi. (Please follow me.) — polite
For this reason, learning imperative particles is just as important as learning the verb itself.

Key Point

Vietnamese does not have a special imperative verb form. The basic verb remains unchanged, while particles determine whether the sentence is a command, prohibition, request, suggestion, or encouragement. hãy commonly introduces instructions, đừng forms negative commands, nhé softens requests, đi encourages an action, and expressions such as xin, làm ơn, and vui lòng make requests more polite. Learning combinations such as Hãy nghe (Listen), Đừng đi (Don't go), Ngồi đi (Sit down), and Đợi tôi nhé (Wait for me, okay?) provides a practical foundation for Vietnamese imperatives.

Passives in Vietnamese

Vietnamese does not have a special passive verb form. Verbs remain unchanged, and passive meaning is usually expressed with words such as bị (to suffer; passive marker, often for negative events) and được (to receive; passive marker, often for positive or favorable events). In many situations, Vietnamese also prefers active or topic-based sentences instead of a formal passive construction.

Basic Passive Structure

A common passive pattern is:
subject + bị/được + verb
For example:
Tôi bị thương. (I was injured.)
Cô ấy được khen. (She was praised.)
Anh ấy bị phạt. (He was punished.)
The main verb does not change.

No Passive Conjugation

Vietnamese verbs have the same form in active and passive sentences.
Compare:
Giáo viên khen cô ấy. (The teacher praises her.)
Cô ấy được khen. (She is praised.)
The verb khen (to praise) remains unchanged.
Similarly:
Họ phạt anh ấy. (They punish him.)
Anh ấy bị phạt. (He is punished.)

Bị

bị commonly introduces passive situations that are unpleasant, unwanted, accidental, or disadvantageous.
For example:
Tôi bị mất điện thoại. (I lost my phone; my phone was lost/stolen, depending on context.)
Anh ấy bị sa thải. (He was fired.)
Cô ấy bị thương. (She was injured.)
Xe bị hỏng. (The vehicle is broken; the vehicle broke down.)
Because of this negative association, bị often conveys more than simple grammatical passivity.

Được

được commonly introduces actions that are beneficial, desirable, permitted, or viewed positively.
For example:
Cô ấy được khen. (She was praised.)
Tôi được mời đến dự tiệc. (I was invited to the party.)
Anh ấy được thăng chức. (He was promoted.)
Chúng tôi được giúp đỡ. (We were helped.)
In many cases, được gives the sentence a positive or favorable meaning.

Positive and Negative Contrast

A useful contrast is:
được + verb — often favorable
bị + verb — often unfavorable
For example:
Anh ấy được thưởng. (He was rewarded.)
Anh ấy bị phạt. (He was punished.)
However, the distinction is not purely grammatical. The speaker's view of the event and the natural meaning of the verb also influence which form is used.

Passive with an Agent

The person or thing performing the action can be included after bị or được.
A common pattern is:
subject + bị/được + agent + verb
For example:
Cô ấy được giáo viên khen. (She was praised by the teacher.)
Anh ấy bị cảnh sát bắt. (He was arrested by the police.)
Tôi được bạn giúp. (I was helped by a friend.)
The agent normally appears before the main verb.

Passive with Do

In more formal Vietnamese, do (by; because of) can introduce the agent or cause.
For example:
Cuốn sách được viết do một tác giả nổi tiếng. (The book was written by a famous author.)
More naturally, especially in many modern contexts, Vietnamese may also use:
Cuốn sách được một tác giả nổi tiếng viết. (The book was written by a famous author.)
The exact structure depends on style and emphasis.

Past Passive

Past meaning can be shown with time expressions or đã (past/completed action).
For example:
Anh ấy đã bị sa thải. (He was fired; he has been fired.)
Cô ấy đã được mời. (She was invited; she has been invited.)
Hôm qua tôi bị mất ví. (Yesterday I lost my wallet; my wallet was lost/stolen.)
The verb itself still does not change.

Future Passive

Future passive meaning can use sẽ (will).
For example:
Anh ấy sẽ được thăng chức. (He will be promoted.)
Ngôi nhà sẽ được sửa. (The house will be repaired.)
Người vi phạm sẽ bị phạt. (The person who violates the rule will be punished.)
The common order is:
subject + sẽ + bị/được + verb

Negative Passive

Passive sentences can be negated with không (not).
For example:
Anh ấy không bị thương. (He was not injured.)
Cô ấy không được mời. (She was not invited.)
Tôi không bị ảnh hưởng. (I was not affected.)
The exact meaning of không được can also be not permitted to in other structures, so context is important.

Được as Permission

được is not only a passive marker. It can also express permission or possibility.
For example:
Tôi được vào. (I am allowed to enter.)
Bạn được nghỉ hôm nay. (You are allowed to take today off.)
Because được has several functions, learners should interpret it from the whole sentence rather than translating it automatically as be.

Bị as Experiencing Something Negative

Similarly, bị can describe experiencing an undesirable condition rather than a strict passive construction.
For example:
Tôi bị đau đầu. (I have a headache.)
Anh ấy bị cảm. (He has a cold.)
Cô ấy bị sốt. (She has a fever.)
These expressions are grammatically related to the idea of undergoing or suffering something, even though English does not normally translate them as passives.

Passive Without Bị or Được

Vietnamese does not always need bị or được to express an idea that English would phrase passively.
For example:
Nhà xây năm 1990. (The house was built in 1990.)
In appropriate contexts, Vietnamese can simply place the topic first and let the situation make the passive interpretation clear.
This is especially common when the agent is unimportant or already understood.

Active Sentences Instead of Passive

Vietnamese often prefers an active sentence where English might naturally use a passive.
For example:
Người ta xây cây cầu này năm ngoái. (They built this bridge last year; This bridge was built last year.)
The expression người ta (people; they; one) is frequently used when the identity of the agent is general or unimportant.

Passive with Objects

The object of an active sentence can become the topic or subject of a passive construction.
Active:
Công ty tuyển cô ấy. (The company hired her.)
Passive:
Cô ấy được công ty tuyển. (She was hired by the company.)
Active:
Cảnh sát bắt anh ấy. (The police arrested him.)
Passive:
Anh ấy bị cảnh sát bắt. (He was arrested by the police.)
The main verb remains identical.

Common Passive Verbs

Useful combinations include:
bị bắt (be arrested)
bị phạt (be punished; be fined)
bị thương (be injured)
bị sa thải (be fired)
bị mất (be lost; suffer the loss of)
được khen (be praised)
được mời (be invited)
được giúp (be helped)
được chọn (be chosen)
được thăng chức (be promoted)
được chấp nhận (be accepted)
These combinations are often best learned as complete expressions.

Passive in Formal Writing

Passive constructions with được and bị are common in news, official documents, academic writing, and formal descriptions.
For example:
Dự án được hoàn thành năm ngoái. (The project was completed last year.)
Luật mới được thông qua. (The new law was passed.)
Nhiều người bị ảnh hưởng. (Many people were affected.)
Formal Vietnamese may use passive constructions more frequently than casual conversation.

Passive in Everyday Speech

In conversation, speakers often choose the structure that best reflects how they feel about the event.
For example:
Tôi được tặng một món quà. (I was given a gift.)
emphasizes receiving something positive.
By contrast:
Tôi bị lấy mất điện thoại. (My phone was taken from me.)
emphasizes an unwanted experience.
This emotional dimension is an important feature of Vietnamese passive expressions.

Asking Passive Questions

Questions can be formed without changing the verb.
For example:
Bạn có được mời không? (Were you invited?)
Anh ấy có bị thương không? (Was he injured?)
Ai được chọn? (Who was chosen?)
Tại sao cô ấy bị phạt? (Why was she punished?)
The words bị and được remain in the same position as in statements.

Passive and Time Expressions

Time expressions can appear naturally with passive structures:
Hôm qua anh ấy bị bắt. (Yesterday he was arrested.)
Tuần trước cô ấy được thăng chức. (Last week she was promoted.)
Ngày mai kết quả sẽ được công bố. (Tomorrow the results will be announced.)
Tense is therefore shown through context and markers rather than changes to the verb.

Key Point

Vietnamese does not form the passive by changing the verb. Instead, bị is commonly used when someone undergoes an unpleasant or unwanted event, while được often describes a favorable or beneficial event. The main verb always remains unchanged, as in bị phạt (be punished), bị thương (be injured), được khen (be praised), and được mời (be invited). Vietnamese also frequently avoids passive constructions altogether when an active or topic-based sentence sounds more natural.

Negation in Vietnamese

Vietnamese negation is relatively simple because verbs and adjectives do not change form. Negative meaning is mainly expressed with words such as không (not; no), chưa (not yet), đừng (do not), and chẳng (not; hardly). The correct choice depends on whether the sentence describes a fact, an unfinished action, a prohibition, or emphasis.

Không

không is the most common Vietnamese negative word and normally appears before a verb or adjective.
For example:
Tôi không biết. (I do not know.)
Anh ấy không đi. (He is not going; he does not go.)
Cô ấy không mệt. (She is not tired.)
Nhà này không lớn. (This house is not big.)
The verb or adjective remains unchanged.

Basic Negative Structure

The most common pattern is:
subject + không + verb/adjective
For example:
Tôi không uống cà phê. (I do not drink coffee.)
Cô ấy không sống ở đây. (She does not live here.)
Bài này không khó. (This exercise is not difficult.)
There is no equivalent of auxiliary verbs such as do or does in these simple negative sentences.

Không Có

When negating possession or existence, Vietnamese commonly uses không có (do not have; there is not).
For example:
Tôi không có xe. (I do not have a car.)
Cô ấy không có thời gian. (She does not have time.)
Ở đây không có nhà hàng. (There is no restaurant here.)
The combination không có is extremely common in everyday speech.

Chưa

chưa means not yet and indicates that an action or situation has not happened up to the present moment but may happen later.
For example:
Tôi chưa ăn. (I have not eaten yet.)
Anh ấy chưa đến. (He has not arrived yet.)
Chúng tôi chưa quyết định. (We have not decided yet.)
This is different from simple không, which usually expresses general or straightforward negation.

Không and Chưa

Compare:
Tôi không ăn. (I do not eat; I am not eating.)
Tôi chưa ăn. (I have not eaten yet.)
The first sentence simply negates the action. The second suggests that eating may still happen later.
Another example:
Anh ấy không đến. (He is not coming; he did not come.)
Anh ấy chưa đến. (He has not arrived yet.)

Chưa ... Bao Giờ

The combination chưa bao giờ means never when referring to experience up to the present.
For example:
Tôi chưa bao giờ đến Việt Nam. (I have never been to Vietnam.)
Cô ấy chưa bao giờ ăn phở. (She has never eaten phở.)
This structure is especially common when talking about life experiences.

Không Bao Giờ

không bao giờ also means never, especially when describing habits, intentions, or general statements.
For example:
Tôi không bao giờ hút thuốc. (I never smoke.)
Anh ấy không bao giờ đến muộn. (He is never late.)
Tôi sẽ không bao giờ quên. (I will never forget.)

Chẳng

chẳng is another negative word meaning not, does not, or sometimes hardly. It can sound stronger, more expressive, or more literary than ordinary không.
For example:
Tôi chẳng biết. (I really do not know.)
Anh ấy chẳng nói gì. (He does not say anything.)
In normal beginner conversation, không is generally the safest choice.

Chẳng Bao Giờ

chẳng bao giờ means never and often carries stronger emphasis.
For example:
Tôi chẳng bao giờ quên chuyện đó. (I will never forget that.)
It is common in emotional or emphatic statements.

Negative Past Sentences

Vietnamese can negate past actions with không, usually together with a past-time expression.
For example:
Hôm qua tôi không đi làm. (Yesterday I did not go to work.)
Tuần trước cô ấy không đến. (Last week she did not come.)
Past meaning comes from the context or time expression rather than from a change in the verb.

Đã Không

đã không can be used when explicitly emphasizing that something did not happen or was not true in the past.
For example:
Tôi đã không đi. (I did not go.)
Anh ấy đã không trả lời. (He did not answer.)
However, Vietnamese often prefers a clear past-time expression with simple không instead.

Negative Future Sentences

Future negation normally uses:
sẽ + không + verb
For example:
Tôi sẽ không đi. (I will not go.)
Cô ấy sẽ không đến. (She will not come.)
Chúng tôi sẽ không quên. (We will not forget.)
The verb remains unchanged.

Negative Commands

Negative commands are usually formed with đừng (do not).
The basic pattern is:
đừng + verb
For example:
Đừng đi! (Don't go!)
Đừng nói! (Don't speak!)
Đừng lo. (Don't worry.)
Đừng quên. (Don't forget.)
Using không instead of đừng does not normally create the same imperative meaning.

Đừng ... Nữa

To tell someone to stop an action, Vietnamese frequently uses đừng ... nữa (do not ... anymore).
For example:
Đừng nói nữa. (Stop talking.)
Đừng khóc nữa. (Don't cry anymore.)
Đừng làm việc nữa. (Stop working.)
The word nữa emphasizes that the action should no longer continue.

Không Còn

không còn means no longer, not anymore, or there is no longer.
For example:
Tôi không còn sống ở Hà Nội. (I no longer live in Hanoi.)
Anh ấy không còn làm việc ở đây. (He no longer works here.)
Không còn cà phê. (There is no coffee left.)
It indicates that something was previously true but has now ended.

Chưa ... Xong

Vietnamese often combines chưa with xong (finished) to indicate that an action is not yet complete.
For example:
Tôi chưa làm xong. (I have not finished yet.)
Cô ấy chưa đọc xong cuốn sách. (She has not finished reading the book yet.)
This is a common way to talk about unfinished activities.

Nothing

The expression không ... gì can mean nothing or not anything.
For example:
Tôi không biết gì. (I do not know anything.)
Anh ấy không nói gì. (He did not say anything.)
Tôi không thấy gì. (I cannot see anything.)
The negative word appears before the verb while gì (what; anything) usually follows it.

Nobody

Vietnamese can express nobody using combinations such as không ai (nobody; no one).
For example:
Không ai biết. (Nobody knows.)
Không ai đến. (Nobody came.)
Tôi không gặp ai. (I did not meet anyone.)
The position of ai (who; anyone) depends on its grammatical role.

Nowhere

không đâu can express nowhere or strong negation in some contexts, while location questions use ở đâu (where).
For example:
Tôi không đi đâu. (I am not going anywhere.)
Anh ấy không ở đâu cả. (He is nowhere; he is not anywhere.)
The exact form depends on the sentence and emphasis.

Không ... Cả

The particle cả can strengthen a negative statement and often contributes meanings such as at all, any, or none.
For example:
Tôi không biết gì cả. (I do not know anything at all.)
Không ai đến cả. (Nobody came at all.)
Tôi không có tiền cả. (I have no money at all.)
It is common in emphatic conversational negation.

Neither ... Nor

Vietnamese can express neither ... nor with structures involving không ... cũng không.
For example:
Tôi không uống cà phê, cũng không uống trà. (I drink neither coffee nor tea.)
Anh ấy không gọi, cũng không nhắn tin. (He neither called nor sent a message.)
The repeated negative structure makes both elements negative.

Not Very

To soften a negative judgment, Vietnamese commonly uses không ... lắm (not very).
For example:
Không đẹp lắm. (Not very beautiful.)
Tôi không khỏe lắm. (I am not very well.)
Món này không ngon lắm. (This dish is not very tasty.)
This is often more natural and polite than using a strongly negative adjective.

Not Really

Expressions such as không hẳn (not exactly; not necessarily; not really) are useful for partial disagreement.
For example:
Không hẳn. (Not exactly.)
Điều đó không hẳn đúng. (That is not entirely true.)
It softens the negation and leaves room for nuance.

Negative Questions

Vietnamese can form negative questions with không or chưa.
For example:
Bạn không đi à? (Aren't you going?)
Anh ấy chưa đến à? (Hasn't he arrived yet?)
Questions with chưa often ask whether an expected action has happened:
Bạn ăn chưa? (Have you eaten yet?)
Possible answers include:
Rồi. (Yes; already.)
Chưa. (Not yet.)

Có ... Không?

A common yes-or-no question pattern is:
có + verb/adjective + không?
For example:
Bạn có hiểu không? (Do you understand?)
Cô ấy có khỏe không? (Is she well?)
Although không appears in the question, it does not automatically make the whole sentence negative. Instead, the structure asks whether something is true or not.

Không Phải

không phải means is not, are not, or not the case and is especially important when negating identification or classification.
For example:
Tôi không phải là bác sĩ. (I am not a doctor.)
Đây không phải là nhà tôi. (This is not my house.)
Anh ấy không phải người Việt Nam. (He is not Vietnamese.)
This differs from ordinary adjective negation:
Anh ấy không cao. (He is not tall.)

Không Được

không được can mean must not, may not, or not allowed to.
For example:
Không được hút thuốc. (No smoking; You must not smoke.)
Bạn không được vào. (You are not allowed to enter.)
Không được nói chuyện. (Talking is not allowed.)
This construction is stronger than a simple negative statement because it expresses prohibition.

Negative Adjectives

Adjectives are negated directly with không:
không đẹp (not beautiful)
không tốt (not good)
không khó (not difficult)
không đắt (not expensive)
For example:
Khách sạn này không đắt. (This hotel is not expensive.)
No verb meaning to be is required before ordinary adjectives.

Negative Verb Combinations

When several verbs appear together, không is generally placed before the element being negated.
For example:
Tôi không muốn đi. (I do not want to go.)
Tôi muốn không đi. (I want not to go, uncommon and highly context-dependent.)
The placement of the negative word therefore affects the meaning.

Common Negative Expressions

Useful everyday forms include:
không biết (do not know)
không hiểu (do not understand)
không có (do not have; there is not)
không muốn (do not want)
không thể (cannot)
chưa biết (do not know yet)
chưa ăn (have not eaten yet)
không bao giờ (never)
không còn (no longer)
đừng lo (don't worry)
These expressions appear constantly in spoken Vietnamese.

Key Point

Vietnamese negation is mainly expressed through separate words rather than changes to verbs or adjectives. không is the general word for not, chưa means not yet, đừng forms negative commands, không còn expresses no longer, and không phải is commonly used to negate identity or classification. The difference between forms such as không ăn (do not eat), chưa ăn (have not eaten yet), and đừng ăn (do not eat!) is essential for expressing negative meaning accurately and naturally in Vietnamese.

Modal Verbs in Vietnamese

Vietnamese uses several verbs and particles to express ability, possibility, necessity, obligation, permission, intention, desire, and probability. These forms behave somewhat like modal verbs in English, but Vietnamese modal verbs never change according to person, number, or tense. They normally appear before the main verb.

Basic Structure

A common pattern is:
subject + modal verb + main verb
For example:
Tôi có thể đi. (I can go.)
Cô ấy muốn học. (She wants to study.)
Anh ấy phải làm việc. (He must work.)
The main verb remains unchanged.

Có Thể

có thể means can, may, or be able to and expresses ability or possibility.
For example:
Tôi có thể nói tiếng Việt. (I can speak Vietnamese.)
Bạn có thể giúp tôi. (You can help me.)
Ngày mai trời có thể mưa. (It may rain tomorrow.)
The precise meaning depends on context.

Không Thể

The negative form of có thể is commonly không thể (cannot; impossible to).
For example:
Tôi không thể đi. (I cannot go.)
Anh ấy không thể đến hôm nay. (He cannot come today.)
Chúng tôi không thể chờ lâu hơn. (We cannot wait any longer.)

Có Thể ... Không?

có thể is also extremely useful for polite requests.
For example:
Bạn có thể giúp tôi không? (Can you help me?)
Anh có thể nói chậm hơn không? (Can you speak more slowly?)
Tôi có thể vào không? (Can I come in?)
This structure can express either ability or permission depending on the situation.

Phải

phải expresses necessity or obligation and commonly means must, have to, or need to.
For example:
Tôi phải đi làm. (I have to go to work.)
Bạn phải học. (You must study.)
Chúng tôi phải rời đi sớm. (We have to leave early.)
The strength of the obligation depends partly on context.

Không Phải and Không Cần

Learners should not normally use không phải to mean do not have to because không phải often means is not or not the case.
To express lack of necessity, Vietnamese commonly uses không cần (do not need to).
For example:
Bạn không cần đi. (You do not need to go.)
Anh ấy không cần chờ. (He does not need to wait.)
This differs from prohibition.

Không Được

không được commonly expresses prohibition and can mean must not, may not, or not allowed to.
For example:
Bạn không được vào. (You are not allowed to enter.)
Không được hút thuốc. (Smoking is not allowed; You must not smoke.)
Trẻ em không được chơi ở đây. (Children are not allowed to play here.)
It is stronger than không cần, which simply means something is unnecessary.

Cần

cần means to need or need to.
For example:
Tôi cần nghỉ ngơi. (I need to rest.)
Bạn cần học thêm. (You need to study more.)
Chúng tôi cần nói chuyện. (We need to talk.)
It can also be followed by a noun:
Tôi cần nước. (I need water.)

Nên

nên expresses advice or recommendation and usually means should or ought to.
For example:
Bạn nên nghỉ ngơi. (You should rest.)
Anh ấy nên đi bác sĩ. (He should go to the doctor.)
Chúng ta nên bắt đầu sớm. (We should start early.)
It is generally weaker than phải.

Không Nên

không nên means should not.
For example:
Bạn không nên hút thuốc. (You should not smoke.)
Anh ấy không nên lái xe quá nhanh. (He should not drive too fast.)
Chúng ta không nên đến muộn. (We should not arrive late.)
Compare không nên (should not) with không được (must not; not allowed to).

Muốn

muốn means to want and expresses desire or intention.
For example:
Tôi muốn ăn. (I want to eat.)
Cô ấy muốn học tiếng Việt. (She wants to learn Vietnamese.)
Chúng tôi muốn đi Hà Nội. (We want to go to Hanoi.)
The following verb stays in its basic form.

Muốn Có

When the desired object is a noun rather than an action, Vietnamese often uses muốn có (want to have).
For example:
Tôi muốn có một chiếc xe mới. (I want to have a new car.)
Cô ấy muốn có thêm thời gian. (She wants to have more time.)
In many contexts, however, simple muốn can also introduce a noun naturally.

Định

định expresses intention or a plan and can mean intend to or plan to.
For example:
Tôi định đi Việt Nam. (I intend to go to Vietnam.)
Bạn định làm gì? (What are you planning to do?)
Cô ấy định học thêm tiếng Việt. (She plans to study more Vietnamese.)
It is especially common when talking about personal plans.

Dự Định

dự định also means to plan or to intend and is often slightly more explicit than định.
For example:
Tôi dự định chuyển đến Hà Nội. (I plan to move to Hanoi.)
Chúng tôi dự định đi du lịch năm sau. (We plan to travel next year.)

Sắp

sắp expresses an action that is about to happen.
For example:
Tôi sắp đi. (I am about to leave.)
Trời sắp mưa. (It is about to rain.)
Cuộc họp sắp bắt đầu. (The meeting is about to begin.)
It normally appears immediately before the verb or predicate.

Sẽ

sẽ is commonly used to express future meaning and can function similarly to will.
For example:
Tôi sẽ gọi cho bạn. (I will call you.)
Anh ấy sẽ đến ngày mai. (He will come tomorrow.)
Chúng tôi sẽ giúp. (We will help.)
Vietnamese often omits sẽ when the future time is already obvious.

Dám

dám means to dare or dare to.
For example:
Tôi không dám hỏi. (I do not dare to ask.)
Anh ấy dám nói điều đó. (He dares to say that.)
The negative form không dám (do not dare) is especially common in conversation.

Biết

biết primarily means to know, but before another verb it can indicate knowing how to perform an activity.
For example:
Tôi biết bơi. (I know how to swim.)
Cô ấy biết nấu ăn. (She knows how to cook.)
Bạn biết lái xe không? (Do you know how to drive?)
This is different from có thể, which generally expresses ability or possibility rather than learned skill.

Ability: Biết and Có Thể

Compare:
Tôi biết bơi. (I know how to swim.)
Tôi có thể bơi. (I can swim; I am able to swim.)
biết emphasizes knowledge or learned ability, while có thể emphasizes possibility or capability in a particular situation.

Permission with Được

được can express permission and mean may, can, or be allowed to.
For example:
Tôi được vào. (I am allowed to enter.)
Bạn được nghỉ hôm nay. (You are allowed to take today off.)
To ask permission:
Tôi vào được không? (May I come in?)
Tôi ngồi đây được không? (Can I sit here?)
The position of được can vary according to its function.

Cần Phải

Vietnamese can combine cần and phải as cần phải (need to; must) to emphasize necessity.
For example:
Chúng ta cần phải nói chuyện. (We need to talk.)
Bạn cần phải cẩn thận. (You need to be careful.)
In many everyday sentences, either cần or phải alone is sufficient.

Có Lẽ

có lẽ means perhaps, maybe, or probably and expresses uncertainty.
For example:
Có lẽ anh ấy sẽ đến. (Perhaps he will come.)
Có lẽ trời sẽ mưa. (Maybe it will rain.)
It often appears at the beginning of the sentence.

Chắc

chắc can mean probably, likely, or sure, depending on context.
For example:
Anh ấy chắc sẽ đến. (He will probably come.)
Ngày mai chắc trời mưa. (It will probably rain tomorrow.)
The stronger form chắc chắn means certainly or definitely.

Multiple Modal Expressions

Vietnamese can combine modal expressions in the same sentence.
For example:
Tôi có thể sẽ đi. (I may go.)
Anh ấy chắc sẽ đến. (He will probably come.)
Bạn nên cố gắng học thêm. (You should try to study more.)
Chúng tôi có thể phải chờ. (We may have to wait.)
Word order determines how the different meanings relate to one another.

Modal Verbs with Negation

Negation usually appears before the modal or main verb depending on what is being negated.
For example:
Tôi không muốn đi. (I do not want to go.)
Tôi không thể đi. (I cannot go.)
Bạn không cần đi. (You do not need to go.)
Bạn không nên đi. (You should not go.)
The position of không is therefore important.

Modal Verbs in Questions

Modal expressions are commonly used with không to form questions.
For example:
Bạn có thể giúp tôi không? (Can you help me?)
Tôi có cần đặt trước không? (Do I need to book in advance?)
Chúng ta có nên đi không? (Should we go?)
Bạn muốn ăn gì? (What do you want to eat?)
These patterns are extremely useful in everyday communication.

Common Modal Expressions

Important forms include:
có thể (can; may)
phải (must; have to)
cần (need to)
cần phải (need to; must)
nên (should)
được (may; be allowed to)
muốn (want to)
định (intend to)
sẽ (will)
sắp (be about to)
dám (dare to)
biết (know how to)
có lẽ (perhaps)
chắc (probably)

Key Point

Vietnamese modal verbs and particles do not change form. They are normally placed before another verb to add meanings such as ability, necessity, permission, intention, or probability. có thể expresses ability or possibility, phải expresses obligation, cần expresses necessity, nên gives advice, được can express permission, and muốn expresses desire. Important contrasts include không cần đi (do not need to go), không nên đi (should not go), and không được đi (must not go; not allowed to go). Learning these combinations makes it possible to express a wide range of ideas without conjugating the main verb.

Conjunctions in Vietnamese

Vietnamese conjunctions connect words, phrases, and clauses and express relationships such as addition, contrast, cause, result, condition, choice, and sequence. They do not change form, and many Vietnamese conjunctions can appear either alone or as part of paired structures.

Và

và means and and is the most common conjunction for joining similar elements.
For example:
cà phê và trà (coffee and tea)
Tôi học tiếng Việt và tiếng Anh. (I study Vietnamese and English.)
Cô ấy thông minh và thân thiện. (She is intelligent and friendly.)
It is common in both spoken and written Vietnamese.

Với

với primarily means with, but in some contexts it can also connect nouns in a way similar to and.
For example:
tôi với bạn (you and I; me and you)
Anh ấy đi với bạn. (He goes with a friend.)
In formal writing, và is generally more neutral for simple coordination.

Hoặc

hoặc means or and presents alternatives.
For example:
trà hoặc cà phê (tea or coffee)
Bạn có thể đi hôm nay hoặc ngày mai. (You can go today or tomorrow.)
Chúng ta ăn ở nhà hoặc đi nhà hàng. (We can eat at home or go to a restaurant.)

Hay

hay can also mean or, especially in questions and everyday conversation.
For example:
Bạn muốn trà hay cà phê? (Do you want tea or coffee?)
Bạn đi xe buýt hay tàu? (Are you going by bus or train?)
In this use, hay commonly asks the listener to choose between alternatives.

Nhưng

nhưng means but and introduces a contrast.
For example:
Tôi muốn đi nhưng tôi không có thời gian. (I want to go, but I do not have time.)
Nhà nhỏ nhưng đẹp. (The house is small but beautiful.)
Anh ấy mệt nhưng vẫn làm việc. (He is tired but still works.)

Tuy ... Nhưng

Vietnamese frequently uses the paired structure tuy ... nhưng ... (although ... nevertheless/but ...).
For example:
Tuy trời mưa nhưng chúng tôi vẫn đi. (Although it is raining, we are still going.)
Tuy khó nhưng bài này rất thú vị. (Although difficult, this exercise is very interesting.)
In everyday speech, one part of the pair may sometimes be omitted.

Mặc Dù

mặc dù means although; even though and introduces a concession.
For example:
Mặc dù mệt, cô ấy vẫn làm việc. (Although she is tired, she still works.)
Mặc dù trời lạnh, chúng tôi vẫn đi bộ. (Although it is cold, we still walk.)
It is common in both conversation and formal writing.

Vì

vì means because or because of and introduces a reason.
For example:
Tôi ở nhà vì trời mưa. (I stay home because it is raining.)
Cô ấy nghỉ làm vì bị ốm. (She takes time off work because she is sick.)
vì can introduce either a clause or, in many contexts, a noun phrase expressing the cause.

Bởi Vì

bởi vì also means because and is often slightly more explicit than simple vì.
For example:
Tôi không đi bởi vì tôi rất mệt. (I am not going because I am very tired.)
In ordinary conversation, vì is often sufficient.

Vì ... Nên

A very common cause-and-result structure is:
vì ... nên ... (because ... therefore ...)
For example:
Vì trời mưa nên tôi ở nhà. (Because it is raining, I stay home.)
Vì anh ấy mệt nên anh ấy đi ngủ sớm. (Because he is tired, he goes to bed early.)
Vietnamese can explicitly mark both the cause and the result in the same sentence.

Nên

nên can mean therefore; so when it introduces a consequence.
For example:
Trời mưa nên chúng tôi không đi. (It is raining, so we are not going.)
It can also mean should in modal constructions, so context determines its function.

Do

do means because of; due to and is particularly common in formal or written Vietnamese.
For example:
Chuyến bay bị hoãn do thời tiết xấu. (The flight was delayed because of bad weather.)
Cuộc họp bị hủy do mưa lớn. (The meeting was canceled due to heavy rain.)

Nếu

nếu means if and introduces a condition.
For example:
Nếu trời mưa, tôi sẽ ở nhà. (If it rains, I will stay home.)
Nếu bạn có thời gian, hãy gọi cho tôi. (If you have time, call me.)
The verb does not change form inside the conditional clause.

Nếu ... Thì

Vietnamese often uses nếu ... thì ... (if ... then ...).
For example:
Nếu bạn mệt thì hãy nghỉ. (If you are tired, then rest.)
Nếu ngày mai trời đẹp thì chúng ta sẽ đi biển. (If the weather is good tomorrow, we will go to the beach.)
The word thì (then) is often optional when the relationship is already clear.

Khi

khi means when and connects an action with a time or situation.
For example:
Khi tôi về nhà, cô ấy đang ngủ. (When I came home, she was sleeping.)
Gọi cho tôi khi bạn đến. (Call me when you arrive.)
It can refer to past, present, or future situations depending on context.

Trong Khi

trong khi means while; whereas.
For example:
Tôi đọc sách trong khi cô ấy xem TV. (I read while she watches TV.)
It can also introduce contrast:
Anh ấy thích cà phê, trong khi tôi thích trà. (He likes coffee, whereas I like tea.)

Trước Khi

trước khi means before when followed by an action or clause.
For example:
Tôi uống cà phê trước khi đi làm. (I drink coffee before going to work.)
Hãy gọi cho tôi trước khi bạn đến. (Call me before you arrive.)

Sau Khi

sau khi means after when connecting two actions.
For example:
Sau khi ăn, chúng tôi đi dạo. (After eating, we go for a walk.)
Tôi sẽ gọi cho bạn sau khi làm việc xong. (I will call you after I finish work.)

Rồi

rồi can help connect actions in sequence and may correspond to then in certain contexts.
For example:
Tôi ăn sáng rồi đi làm. (I eat breakfast and then go to work.)
It also has other meanings, including already, so its interpretation depends on the sentence.

Sau Đó

sau đó means after that; then and is useful for connecting events.
For example:
Chúng tôi ăn tối, sau đó đi xem phim. (We have dinner, then go to the cinema.)
It is especially common in narratives and instructions.

Còn

còn has several functions and can connect contrasting information, often with a meaning similar to while; whereas; as for.
For example:
Tôi thích cà phê, còn cô ấy thích trà. (I like coffee, whereas she likes tea.)
It is very common when contrasting two people, objects, or situations.

Cũng

cũng means also; too and can help connect similar information across clauses.
For example:
Tôi thích phở. Cô ấy cũng thích phở. (I like phở. She likes phở too.)
Although it is often classified as an adverb, it performs an important connecting role in Vietnamese sentences.

Không Chỉ ... Mà Còn

The structure không chỉ ... mà còn ... means not only ... but also ....
For example:
Cô ấy không chỉ nói tiếng Việt mà còn nói tiếng Anh. (She not only speaks Vietnamese but also English.)
Hà Nội không chỉ đẹp mà còn rất thú vị. (Hanoi is not only beautiful but also very interesting.)
This structure is common in both spoken and written Vietnamese.

Vừa ... Vừa

vừa ... vừa ... can mean both ... and ... when two characteristics or actions occur together.
For example:
Cô ấy vừa thông minh vừa thân thiện. (She is both intelligent and friendly.)
Anh ấy vừa học vừa làm. (He both studies and works.)
It is especially useful for describing simultaneous qualities or activities.

Càng ... Càng

The paired structure càng ... càng ... means the more ... the more ....
For example:
Càng học càng hiểu. (The more you study, the more you understand.)
Càng nói tiếng Việt nhiều, bạn càng tiến bộ. (The more Vietnamese you speak, the more you improve.)
This is a common structure for expressing proportional change.

Hoặc ... Hoặc

hoặc ... hoặc ... means either ... or ....
For example:
Bạn có thể hoặc đi hôm nay hoặc đi ngày mai. (You can either go today or tomorrow.)
In many everyday sentences, a single hoặc is enough.

Dù ... Vẫn

dù ... vẫn ... means even though ... still ....
For example:
Dù mệt, anh ấy vẫn làm việc. (Even though he is tired, he still works.)
Dù trời mưa, chúng tôi vẫn đi. (Even though it is raining, we still go.)
The word vẫn emphasizes that the result continues despite the condition.

Để

để means in order to; so that and introduces purpose.
For example:
Tôi học tiếng Việt để nói chuyện với bạn bè. (I study Vietnamese in order to speak with friends.)
Cô ấy đi sớm để không đến muộn. (She leaves early so that she will not arrive late.)
It is one of the most common ways to connect an action with its purpose.

Common Conjunction Patterns

Useful Vietnamese conjunctions include:
và (and)
hoặc (or)
hay (or, especially in questions)
nhưng (but)
vì (because)
nên (so; therefore)
nếu (if)
khi (when)
trong khi (while; whereas)
trước khi (before)
sau khi (after)
mặc dù (although)
để (in order to)
Common paired structures include:
vì ... nên ... (because ... therefore ...)
nếu ... thì ... (if ... then ...)
tuy ... nhưng ... (although ... but ...)
không chỉ ... mà còn ... (not only ... but also ...)
vừa ... vừa ... (both ... and ...)
càng ... càng ... (the more ... the more ...)

Key Point

Vietnamese conjunctions are simple in form but very important for building longer and more natural sentences. và joins ideas, nhưng introduces contrast, vì gives a reason, nên introduces a result, nếu expresses a condition, and để introduces purpose. Paired structures such as vì ... nên ... (because ... therefore ...), nếu ... thì ... (if ... then ...), and không chỉ ... mà còn ... (not only ... but also ...) are especially useful for connecting ideas clearly without changing the form of any verb.

Word Order in Vietnamese

Vietnamese word order is generally clear and predictable. The most common sentence pattern is subject + verb + object, but time expressions, adverbs, classifiers, adjectives, and question words follow their own placement rules. Because Vietnamese words do not usually change form, word order is especially important for showing grammatical relationships.

Basic Sentence Order

The most common Vietnamese sentence structure is:
subject + verb + object
For example:
Tôi uống cà phê. (I drink coffee.)
Cô ấy đọc sách. (She reads books.)
Anh ấy học tiếng Việt. (He studies Vietnamese.)
The order usually tells the listener who performs the action and what receives it.

Subject Before the Verb

The subject normally appears before the verb.
For example:
Tôi làm việc. (I work.)
Anh ấy ngủ. (He sleeps.)
Chúng tôi học. (We study.)
However, Vietnamese can omit the subject when it is already obvious from context:
Biết rồi. (I know; understood.)
Đang ăn. (I am eating.)
This is very common in conversation.

Objects After the Verb

Direct objects normally follow the verb.
For example:
Tôi đọc sách. (I read books.)
Cô ấy mua xe. (She buys a car.)
Anh ấy uống nước. (He drinks water.)
A longer object remains after the verb:
Tôi học tiếng Việt mỗi ngày. (I study Vietnamese every day.)

Adjectives After Nouns

Vietnamese adjectives usually follow the nouns they describe.
For example:
nhà đẹp (beautiful house)
xe mới (new car)
người trẻ (young person)
bài tập khó (difficult exercise)
This differs from languages in which adjectives normally come before nouns.

Demonstratives After Nouns

Demonstratives such as này (this), đó (that), and kia (that over there) normally follow the noun.
For example:
nhà này (this house)
xe đó (that car)
người kia (that person over there)
When an adjective is also present, it normally comes before the demonstrative:
ngôi nhà đẹp này (this beautiful house)

Numbers and Classifiers

When counting nouns, Vietnamese usually follows the pattern:
number + classifier + noun
For example:
một cái bàn (one table)
hai con mèo (two cats)
ba người bạn (three friends)
bốn quyển sách (four books)
The classifier comes between the number and the noun.

Possession

Possession is commonly expressed with:
noun + của + possessor
For example:
nhà của tôi (my house)
xe của anh ấy (his car)
sách của giáo viên (the teacher's book)
In common expressions, của may be omitted:
mẹ tôi (my mother)
nhà tôi (my house; my home)

Time Expressions

Time expressions often appear at the beginning of the sentence.
For example:
Hôm nay tôi làm việc ở nhà. (Today I work at home.)
Ngày mai chúng tôi đi Hà Nội. (Tomorrow we are going to Hanoi.)
Tuần trước cô ấy đến Huế. (Last week she went to Hue.)
They can also appear later when the meaning remains clear:
Tôi gặp anh ấy hôm qua. (I met him yesterday.)

Place Expressions

Place expressions commonly appear after the verb or object.
For example:
Tôi sống ở Hà Nội. (I live in Hanoi.)
Cô ấy làm việc ở bệnh viện. (She works at a hospital.)
Chúng tôi ăn tối ở nhà hàng. (We have dinner at a restaurant.)
A place phrase can also be moved to the beginning for emphasis:
Ở Hà Nội, giao thông rất đông. (In Hanoi, traffic is very busy.)

Time Before Place

A common neutral order is:
time + subject + verb + object + place
For example:
Hôm nay tôi làm việc ở nhà. (Today I work at home.)
Ngày mai chúng tôi ăn tối ở nhà hàng. (Tomorrow we will have dinner at a restaurant.)
Vietnamese word order can be flexible, but this pattern is useful for beginners.

Frequency Adverbs

Frequency adverbs normally appear before the main verb.
For example:
Tôi thường uống cà phê. (I usually drink coffee.)
Cô ấy luôn đến đúng giờ. (She always arrives on time.)
Anh ấy đôi khi đi bộ. (He sometimes walks.)
Common frequency words include:
thường (usually; often)
luôn (always)
đôi khi (sometimes)
hiếm khi (rarely)

Tense and Aspect Markers

Words such as đã (past/completed action), đang (currently; progressive), and sẽ (future marker) normally appear before the main verb.
For example:
Tôi đã ăn. (I ate; I have eaten.)
Tôi đang ăn. (I am eating.)
Tôi sẽ ăn. (I will eat.)
The verb ăn (to eat) does not change.

Negation

không (not) normally appears before the verb or adjective it negates.
For example:
Tôi không biết. (I do not know.)
Cô ấy không đi. (She is not going.)
Nhà này không lớn. (This house is not big.)
With modal expressions, its placement helps determine what is being negated:
Tôi không muốn đi. (I do not want to go.)

Modal Verbs

Modal verbs and expressions normally come before the main verb.
For example:
Tôi muốn đi. (I want to go.)
Bạn nên nghỉ. (You should rest.)
Anh ấy phải làm việc. (He must work.)
Cô ấy có thể giúp. (She can help.)
The main verb remains in its basic form.

Adverbs of Manner

Words describing how an action is performed often come after the verb.
For example:
Anh ấy chạy nhanh. (He runs quickly.)
Cô ấy nói chậm. (She speaks slowly.)
Họ làm việc chăm chỉ. (They work hard.)
Degree words can appear before these expressions:
Anh ấy chạy rất nhanh. (He runs very quickly.)

Degree Words

Words such as rất (very), khá (quite), and hơi (slightly) normally appear before adjectives.
For example:
rất đẹp (very beautiful)
khá khó (quite difficult)
hơi lạnh (slightly cold)
However, quá (too; so) commonly appears after an adjective in exclamations:
Đẹp quá! (So beautiful!)
