Vietnamese possessive có presents a person or thing as possessing, containing, or being associated with something: Tôi có một câu hỏi “I have a question,” Nhà này có ba phòng ngủ “This house has three bedrooms.” Its form never changes for person, number, or tense.
The core order is possessor + có + possessed entity. Possession here is broad: legal ownership, family relationships, body features, available time, opportunities, and parts of a whole can all fit. This page keeps that possessor-first pattern separate from existential có, as in Ở đây có Wi-Fi “There is Wi-Fi here,” which introduces an entity within a location.
The possessive frame
| Possessor | có | Possessed or associated entity | Meaning |
|---|---|---|---|
| Tôi | có | một câu hỏi | I have a question. |
| Chị Lan | có | hai người con | Lan has two children. |
| Nhà này | có | ba phòng ngủ | This house has three bedrooms. |
| Nhóm mình | có | đủ thời gian | Our group has enough time. |
Tôi có một câu hỏi về lịch học tuần sau.
I have a question about next week's class schedule.
Chị ấy có hai người con và một cửa hàng nhỏ.
She has two children and a small shop.
Căn hộ này có ban công nhìn ra sông.
This apartment has a balcony overlooking the river.
The noun phrase after có is a complement selected by the possessive predicate. Vietnamese normally places it directly after có; it does not use an English preposition equivalent to of in this frame.
What counts as possession
Physical ownership is only the simplest case. Vietnamese uses có for a wide range of stable or temporary associations.
Bạn có hộ chiếu không?
Do you have a passport?
Hôm nay tôi có nhiều việc phải làm.
I have a lot of work to do today.
Báo cáo này có ba phần chính.
This report has three main sections.
Cô ấy có kinh nghiệm làm việc với trẻ em.
She has experience working with children.
Family relationships also use có when the point is how many relatives someone has: Tôi có hai anh trai “I have two older brothers.” In a noun phrase, however, Vietnamese often expresses “my older brother” simply as anh trai tôi or anh tôi, not by inserting có.
Characteristics may be packaged as possessed nouns: Anh ấy có giọng nói ấm “He has a warm voice.” But a simple property usually predicates directly: Anh ấy cao “He is tall,” not a word-for-word possessive translation of He has tallness.
Time and viewpoint without conjugation
Có does not become a separate form for has or had. Time expressions and independent particles locate the possession.
Hồi còn ở Huế, tôi có một chiếc xe đạp cũ.
When I was living in Hue, I had an old bicycle.
Tháng sau công ty sẽ có văn phòng mới.
Next month the company will have a new office.
Cuối cùng chúng tôi cũng có đủ thông tin rồi.
At last we have enough information now.
Hồi còn ở Huế establishes past time without changing có. Sẽ presents a future prospect. Sentence-final rồi marks the new relevance of a state that has now been reached. Mới có can mean “have only just acquired” or “have only [a small quantity],” depending on context.
This invariant behavior matches other predicates: tôi đi / họ đi, chị ấy đến / chúng tôi đến, tôi thấy / anh ấy thấy. Vietnamese organizes time around lexical predicates rather than conjugating them.
Negation and questions
Negate possession with không có. Ask a neutral yes–no question with có + possessed entity + không? In Bạn có xe không?, có is the possessive predicate, while không presents the negative alternative; this is not a separate question-particle có placed before another verb.
Tôi không có tiền mặt; tôi chuyển khoản được không?
I don't have cash; can I make a bank transfer?
Anh có thời gian nói chuyện một chút không?
Do you have time to talk for a moment?
A: Chị có vé chưa? B: Có rồi, em tôi mua giúp.
A: Do you have a ticket yet? B: Yes, I do; my younger sibling bought it for me.
A short affirmative answer can be Có or Có rồi, while a negative answer is Không or Không có. Choose a fuller answer when the relationship might be unclear.
Do not confuse possessive có with the polar-question frame around another predicate: Chị có bận không? means “Are you busy?” Here bận is the property predicate; có...không frames the question. There is no possessed object.
Possession versus ownership with của
Vietnamese offers two perspectives on the same relationship:
- Tôi có một chiếc xe. starts with the possessor and introduces a car: “I have a car.”
- Chiếc xe này (là) của tôi. starts with a known car and identifies its owner: “This car is mine.”
Tôi có một chiếc ô, nhưng chiếc ô màu đỏ kia không phải của tôi.
I have an umbrella, but that red umbrella isn't mine.
Use có to present someone's inventory, relationships, or resources. Use của + possessor when identifying who something belongs to. English have and belong to express the same relationship from similarly different directions.
Possession versus existence
Compare the required core patterns:
| Clause | Type | Interpretive question |
|---|---|---|
| Tôi ăn cơm. | event | What do I do? |
| Cô ấy là giáo viên. | classification | What is she? |
| Trời lạnh. | property | What is the weather like? |
| Tôi có một câu hỏi. | possession | What do I have? |
| Ở đây có Wi-Fi. | existence | What is available here? |
The boundary can be flexible with places and organizations. Quán này có Wi-Fi treats the café as having a service; Ở quán này có Wi-Fi frames the café as the location where Wi-Fi exists. Both can describe the same real-world situation, but they package it differently. The dedicated page on Có for Existence develops the location-first pattern.
Khách sạn này có phòng tập, và ở tầng hai có một hồ bơi nhỏ.
This hotel has a gym, and there is a small pool on the second floor.
The first clause describes an amenity belonging to the hotel's inventory. The second introduces a pool at a particular location.
A natural conversation
A: Chiều nay bạn có thời gian không? B: Có, nhưng tôi có cuộc hẹn lúc bốn giờ. A: Vậy mình gặp lúc hai giờ nhé. Quán gần công ty có chỗ ngồi ngoài trời không? B: Có. Ở đó cũng có Wi-Fi, mình làm việc một lúc cũng được.
A: Do you have time this afternoon? B: Yes, but I have an appointment at four. A: Then let's meet at two. Does the café near the office have outdoor seating? B: Yes. There's Wi-Fi there too, so we can work for a while.
The dialogue shifts from personal availability to an appointment, a café's amenity, and existence at a location. Có remains unchanged; the subject or locative frame guides the interpretation.
English have does not always become có
Some English expressions with have use a different Vietnamese predicate:
- “I am twenty” / “I am twenty years old” → Tôi hai mươi tuổi, not tôi có hai mươi tuổi.
- “I have a headache” can naturally be Tôi đau đầu, with đau as a property/state predicate.
- “I am hungry” → Tôi đói, never a possessive translation based on English wording.
- “I had to leave” → Tôi phải đi, where phải expresses necessity.
Tôi đau đầu nên phải về sớm.
I have a headache, so I have to go home early.
Quick decision aid
- A person, organization, object, or place has an associated entity? Use possessor + có + entity.
- You are identifying the owner of a known item? Use item + (là) của + owner.
- You are introducing something present at a location? Use location + có + entity.
- English uses have for age, pain, or obligation? Choose the Vietnamese age, state, or modal predicate instead.
- Need past or future meaning? Add context, a time phrase, or an appropriate particle; never conjugate có.
Key Takeaways
- Possessive có uses the frame possessor + có + possessed or associated entity.
- Ownership with của and existence with a location-first có clause present different perspectives.
- English have does not determine the Vietnamese structure; age, states, and obligations use their own predicates.
Common Mistakes
Mistake 1: copying English word order with an of-phrase.
❌ Tôi có của một câu hỏi.
Incorrect — possessive có takes the possessed noun phrase directly.
✅ Tôi có một câu hỏi.
I have a question.
Mistake 2: using có to state age.
❌ Em tôi có mười tuổi.
Incorrect for the neutral statement 'My sibling is ten.'
✅ Em tôi mười tuổi.
My younger sibling is ten.
Mistake 3: confusing possession with owner identification.
❌ Chiếc xe này có tôi.
Incorrect for 'This car is mine.'
✅ Chiếc xe này là của tôi.
This car is mine.
Mistake 4: treating có as conjugated past tense.
❌ Hôm qua tôi có-đã nhiều thời gian.
Incorrect — Vietnamese does not attach a past ending to có.
✅ Hôm qua tôi có nhiều thời gian.
I had plenty of time yesterday.
Each correction restores the Vietnamese predicate frame: direct possession, an age predicate, a của ownership predicate, or an invariant có located in time by context.
