Dạ, vâng and không

What you will learn

Dạ, vâng, không are small words, but they carry important information about politeness and relationships. This lesson helps you hear what each word is doing instead of translating mechanically.

1. Không — no / not

Không is used for “no” and also for negation.

• Không. — No.
• Tôi không biết. — I don’t know.
• Tôi không ăn thịt. — I don’t eat meat.

A bare không can sound abrupt in some situations. Vietnamese often softens a response with a form of address or another polite element.

2. Vâng — a polite yes

Vâng is a polite affirmative response. It is common especially in northern speech and in respectful situations.

• Vâng, tôi hiểu. — Yes, I understand.
• Vâng ạ. — Yes, politely.

3. Dạ — more than “yes”

Dạ is especially important because it does not map perfectly to one English word. It can acknowledge that you heard someone, show respect, prepare a polite answer or accompany yes/no.

• Dạ. — Yes / I’m listening / respectfully acknowledging.
• Dạ, đúng rồi. — Yes, that’s right.
• Dạ không. — No, politely.
• Dạ, con biết rồi. — Yes, I understand, said respectfully in a family context.

4. A short conversation

Cô: Em là sinh viên phải không?

Nam: Dạ, đúng rồi ạ.

Cô: Em học tiếng Việt lâu chưa?

Nam: Dạ chưa. Em mới học.

Cô: Em có hiểu câu này không?

Nam: Dạ, em hiểu.

5. Dạ + yes/no

A useful beginner habit is to recognize combinations:

• dạ có — yes, there is / yes, I have / yes, depending on the question
• dạ không — no, politely
• dạ đúng — yes, correct
• dạ chưa — not yet, politely

Vietnamese answers often repeat the key verb or idea from the question instead of relying only on a universal “yes”.

6. Useful vocabulary

• dạ — respectful acknowledgement/response
• vâng — yes, polite
• không — no / not
• đúng — correct
• đúng rồi — that’s right
• chưa — not yet
• biết — know
• hiểu — understand
• ạ — sentence-final politeness particle

7. Vietnam in real life

Respect in Vietnamese conversation is often distributed across several small choices: the pronoun or kinship term, dạ, the particle ạ, tone of voice and the wording of the answer. That is why translating only the dictionary meaning can miss the social meaning.

8. Common beginner mistake

Do not answer every yes/no question with vâng. Listen to the question. Vietnamese often answers with the relevant word: có, không, đúng, chưa, or a repeated verb.

Try it

1. Say “No, politely” using dạ.
2. Say “Yes, that’s right.”
3. Say “Not yet” politely.
4. Notice one scene in Vietnamese media where a younger person begins an answer with dạ.

Quick recap

Không handles no/negation. Vâng is a polite affirmative. Dạ is a social response that can signal respect and acknowledgement even when “yes” is not the best English translation.
