How to Say No in Vietnamese: Không and Polite Refusals
The basic way to say no in Vietnamese is không. To decline an offer, không, cảm ơn means "no, thank you". For a respectful negative answer to an older person, you can begin with dạ, không. Use chưa for "not yet", when something has not happened.
How to Say No in Vietnamese with Không
Không can stand alone as "no". Before a verb or adjective, it also means "not".
A: Bạn có uống cà phê không? — Do you drink coffee?
B: Không. — No.
You can make the reply more specific: Tôi không uống cà phê means "I do not drink coffee".
The final không in the question helps ask it. The không in the answer supplies the negative meaning.
How to Say No Thank You Politely
Use Không, cảm ơn to decline an offer and thank the person. Add a respectful opening when that fits your relationship.
Decline more food or drink
You are visiting an older woman whom you address as chị. She offers you more tea:
A: Em uống thêm trà không? — Would you like more tea?
B: Dạ, không, em cảm ơn chị. — No, thank you.
Thêm means "more". The reply uses em for the younger speaker and chị for the woman being thanked. Dạ marks respect; không supplies the negative answer.
Decline a purchase
At a shop, you can name the thing you do not want to buy:
A: Bạn có muốn mua cái này không? — Do you want to buy this?
B: Không, cảm ơn. Tôi không mua. — No, thank you. I’m not buying it.
The second sentence makes your decision explicit. You do not have to give a long reason for declining an offer.
A bare không is direct, but it is not automatically rude. Delivery and relationship matter. Vietnamese thank-you phrases give you ways to acknowledge the offer.
Không Phải, Không Được, and Chưa
Use không phải to correct an identification, không được for something not possible or allowed, and chưa for "not yet".
| Vietnamese | English | Context |
|---|---|---|
| Không phải. | No, that’s not right | Correcting an identification |
| Không được. | You can’t; that’s not possible | Permission or feasibility |
| Chưa. | Not yet | Something has not happened yet |
A: Bạn ăn cơm chưa? — Have you eaten yet?
B: Chưa. — Not yet.
If you have not eaten yet, chưa answers this question directly. It says you have not eaten up to now; it does not guarantee that you will eat later.
A word like được changes meaning with context. Use the full sentence if a short answer could be unclear.
Decline an Invitation or Explain Why You Cannot
Name the action in a refusal. Không muốn says you do not want to do it; không thể says you cannot.
| Vietnamese | English | Use |
|---|---|---|
| Tôi không muốn uống bia. | I don’t want to drink beer. | Your preference |
| Tôi không thể đến tối nay. | I can’t come tonight. | You cannot attend |
| Tối nay tôi bận. | I’m busy tonight. | A specific explanation |
Use the meaning that is true. Saying you do not want to go and saying you cannot go give the other person different information.
Turn down an invitation
A friend invites you out. You cannot join tonight:
A: Tối nay bạn đi ăn với tôi được không? — Can you go out to eat with me tonight?
B: Xin lỗi, tối nay tôi bận. Hẹn lần sau nhé. — Sorry, I’m busy tonight. Let’s do it another time.
Bận means "busy". Hẹn lần sau nhé leaves the possibility of another occasion open. Include that last sentence only if you mean it.
You can also say Xin lỗi, tôi không thể đến tối nay. It gives a clear refusal without inventing an excuse. Vietnamese apologies explains how to add a suitable apology.
The examples use tôi and bạn. With someone you call anh or chị, keep the address terms you normally use.
For longer negatives and question patterns, use the Vietnamese grammar reference. In a conversation, one clear reason is often enough to explain your answer.
Pronunciation: The Sounds in Không
Không is one syllable with an unmarked ngang tone. The circumflex on ô marks the vowel, not the tone.
In a Hanoi pronunciation, kh is a friction sound made toward the back of the mouth. Southern pronunciations can start it differently.
In the Hanoi form, begin with a gentle stream of air near the back of your mouth. Keep the vowel and final nasal together instead of breaking the word into "kuh-ong".
The final sound can involve both the back of the tongue and closed lips. That helps explain why you may hear an m-like ending even though the word is written with ng.
Use the word inside a short phrase such as Không, cảm ơn. Keep each Vietnamese syllable distinct. The Vietnamese pronunciation guide explains the regional sound differences.
Choose Between Không, Không Phải, and Chưa
Look at what the question asks you to deny. A mistaken identity, an unfinished action, and a permission request need different answers.
Correct an identification
A: Bạn có phải là giáo viên không? — Are you a teacher?
B: Không phải, tôi là sinh viên. — No, I’m a university student.
Không phải rejects "teacher". The second part supplies the correct information, so the listener knows what to change.
Say something has not happened yet
A: Bạn ăn sáng chưa? — Have you had breakfast yet?
B: Chưa, tôi chưa ăn sáng. — Not yet. I haven’t had breakfast.
The reply describes an action that has not happened up to now. It does not promise that you will eat later. Compare Tôi không ăn sáng, "I don’t eat breakfast".
Refuse permission
A: Tôi ngồi đây được không? — May I sit here?
B: Không được, chỗ này có người rồi. — No, this seat is already taken.
Here, không được answers the request to sit down. The explanation makes the refusal easier to understand.
If someone asks a negative question, a full sentence can prevent confusion. To Bạn không uống trà à?, reply Tôi không uống trà if you do not drink tea.
