Yes in Chinese (and no): how Mandarin answers a question

Mandarin has no all-purpose word for yes or no. You answer a question by repeating its verb: 你去吗? (Nǐ qù ma? — "Are you going?") gets 去 (qù, "go") or 不去 (bú qù, "not go"). The words taught as "yes" — 是, 对, 好 — each covers one specific kind of question.

Why there's no single word for yes in Chinese

English keeps two counters, yes and no, that sit outside the sentence and work for any question. Mandarin has nothing in that slot: agreement is built from the question's own verb, adjective, or modal, so the answer changes every time the question does.

Four exchanges cover most of the system:

• 你喝咖啡吗? Nǐ hē kāfēi ma? — "Do you drink coffee?" → 喝 hē ("I do") or 不喝 bù hē ("I don't").
• 你是学生吗? Nǐ shì xuéshēng ma? — "Are you a student?" → 是 shì or 不是 bú shì.
• 你有零钱吗? Nǐ yǒu língqián ma? — "Do you have change?" → 有 yǒu or 没有 méiyǒu.
• 你吃了吗? Nǐ chī le ma? — "Have you eaten?" → 吃了 chī le or 没吃 méi chī.

Look at the last two. 有 is negated with 没, never 不, and the completed-action marker 了 drops out as soon as 没 appears. Those two habits separate a fluent-sounding answer from a textbook one. The reply is lifted straight out of the question, so word order decides what you're confirming.

The words that do the work of "yes"

A bare verb answers most questions, but a handful of words come up so often they function as near-equivalents. How to say yes in Chinese depends on what you're agreeing to:

• 是 shì — "am/is/are." Confirms identity or category: 你是老板吗? → 是. The longer 是的 shì de sounds slightly more formal and is common on the phone.
• 对 duì — "correct." Confirms that a statement matches the facts: 你姓王，对吗? → 对. Use it to agree with information, not to accept an offer.
• 好 hǎo — "fine, OK." Accepts a suggestion or plan: 我们七点见? → 好.
• 可以 kěyǐ — "may, can." Answers permission questions: 可以拍照吗? → 可以 or 不可以.
• 行 xíng — "works for me." The casual cousin of 好.
• 没错 méi cuò — literally "no error," used the way English uses "that's right."
• 嗯 — a nasal grunt, transcribed ǹg or èn, usually with a nod. Informal and everywhere.

Mixing these up is the most common tell. Answering 我们六点吃饭? ("Shall we eat at six?") with 对 rates the plan as factually correct rather than accepting it; 好 is what a native speaker says.

How to say no in Chinese: 不 vs 没

Negation splits in two. 不 bù is the default negator. 没 méi has exactly two jobs — negating 有 yǒu ("have"), and negating things that did or didn't happen.

What you're negating	Use	Example	Meaning
Ordinary verbs, present or future	不	我不去 wǒ bú qù	I'm not going
Habits and preferences	不	我不喝酒 wǒ bù hē jiǔ	I don't drink
Adjectives	不	不贵 bú guì	not expensive
是 and modals (会, 能, 想, 要)	不	我不会说 wǒ bú huì shuō	I can't speak it
有 ("have," "there is")	没	我没有 wǒ méiyǒu	I don't have any
Completed actions (with 了)	没	我没吃 wǒ méi chī	I haven't eaten
Past experience (with 过)	没	我没去过 wǒ méi qùguo	I've never been

Two rules follow. 不有 doesn't exist in Mandarin — the negative of 有 is always 没有. And 没 can't negate intention: "I'm not going tomorrow" is 我明天不去, not 我明天没去, because nothing has happened yet to negate.

In speech 没有 often collapses to 没, and a bare 不 is a complete, curt refusal.

The tone change on 不 that phrasebooks skip

不 is a fourth tone, bù — except when the next syllable is also a fourth tone, in which case it shifts to second tone, bú. That's why the answer to 你去吗? is bú qù and not bù qù: 去 is fourth tone.

• 不是 → bú shì
• 不对 → bú duì
• 不要 → bú yào
• 不错 → bú cuò
• But 不吃 → bù chī, 不来 → bù lái, 不好 → bù hǎo

Two footnotes. In A-not-A questions like 去不去 qù bu qù, the 不 is unstressed and loses its tone entirely. And written pinyin is inconsistent here — dictionaries usually print the base bù while textbooks print the shifted bú; the spoken form is the same either way. If the shift sounds arbitrary, it's the same mechanism behind the third-tone changes in words like 你好. 没 never changes tone.

Negative questions and A-not-A questions

Chinese asks yes/no questions two ways, and both are answered by echoing.

The 吗 pattern appends 吗 to a statement: 你会说中文吗? → 会 or 不会. The A-not-A pattern repeats the verb around 不 or 没: 你会不会说中文? → same two answers. A-not-A sounds a shade more neutral, since 吗 questions often carry an expectation.

Negative questions are the real trap. Asked 你不去吗? ("You're not going?"), answering 对 agrees with the sentence as stated — "right, I'm not going" — which is the opposite of the English reflex to say "no." Echoing the verb sidesteps the whole problem: 不去 can only mean one thing.

Saying no without sounding blunt

不要 bú yào means "don't want" and is fine among friends, but it lands hard on a stranger. For an offer — more tea, a bag, help with your suitcase — the standard polite refusal is 不用了，谢谢 búyòng le, xièxie, roughly "no need, thanks." In a shop, 我看看 wǒ kànkan ("just looking") declines without a refusal at all. These pair naturally with the rest of the everyday courtesy phrases you'll use daily.

The practical fix at a counter is to learn questions and their answers together rather than as separate vocabulary, which is how Chinese Phrasebook, a Chinese phrasebook app for iPhone, organizes its cards.

FAQ

How do you say yes in Chinese?

There's no single word. You repeat the verb from the question — 你去吗? is answered 去 — or use the confirmation word that fits: 是 for identity, 对 for facts, 好 for plans, 可以 for permission.

Is 是 (shì) the Chinese word for yes?

Not exactly. 是 is the verb "to be," so it only works as "yes" when the question used 是: 你是老师吗? → 是. Use it on 你喜欢吗? and you've answered a question nobody asked.

What's the difference between 不 and 没?

没 negates 有 ("have") and anything already completed or experienced. 不 handles everything else — present, future, habits, adjectives, and modal verbs. The bù vs méi split is grammatical, not a matter of politeness or strength.

How do you politely say no in Chinese?

不用了，谢谢 (búyòng le, xièxie) declines an offer gracefully. 不要 is blunter and better saved for friends or for genuinely refusing something you don't want.

How do you answer a negative question in Chinese?

Repeat the verb rather than reaching for a yes-or-no word. Answering 你不去吗? with 对 confirms the negative statement — "correct, I'm not going" — while 不去 states the fact directly and can't be misread.
