Where Negators and Modals Sit | Chinese (Mandarin) Grammar

Negators (不 bù, 没 méi) and modal verbs (想 want, 要 will, 会 can, 能 be able, 应该 should) share one fixed address in the sentence: after the subject and any time/scope word, but before the whole predicate — that is, ahead of any 在… or 跟… phrase and the main verb, not glued to the verb at the end. The reason is scope: negation and modality apply to everything that follows, so Chinese states them early and lets them reach over the coverb phrase and the verb together. This is why "I don't eat at home" is 我不在家吃饭, with 不 sitting in front of 在, not in front of 吃.

The rule: negator/modal before the coverb phrase

The default order is Subject + (Time) + 不/没 or Modal + [在…/跟…/用…] + Verb. The negator or modal leads the entire predicate.

我不在家吃饭。

wǒ bú zài jiā chī fàn

I don't eat at home. (neutral) — 不 comes before the coverb 在, scoping over 'eat at home'.

他没跟我说这件事。

tā méi gēn wǒ shuō zhè jiàn shì

He didn't tell me about this. (neutral) — 没 sits before 跟, not before 说.

我想在家休息一下。

wǒ xiǎng zài jiā xiūxi yíxià

I want to rest at home for a bit. (informal) — the modal 想 precedes the place phrase 在家.

她没用筷子，用了叉子。

tā méi yòng kuàizi, yòng le chāzi

She didn't use chopsticks; she used a fork. (informal) — 没 before the instrument coverb 用.

Scope matters: where you put 不 changes the meaning

Because 不/没 scope over whatever comes after them, moving the negator moves the meaning. 我不在家吃饭 negates "eat at home" as a whole — I do eat, just not at home. Put 不 after the place, 我在家不吃饭, and it now negates only 吃饭 within the setting "at home" — at home, I don't eat. Both are grammatical; they say different things, and English speakers reaching for "I don't eat at home" almost always want the first.

我不在家工作。

wǒ bú zài jiā gōngzuò

I don't work from home (I work elsewhere). (neutral) — 不 before 在 negates the whole 'work at home'.

我在家不工作，只休息。

wǒ zài jiā bù gōngzuò, zhǐ xiūxi

At home I don't work, I only rest. (informal) — 不 after 在家 negates only 'work' within that setting.

Where they sit in the fuller stack

Relative to the scope words 也 and 都, the negator or modal comes after them: the order is 也/都 → 不/没/modal. And a negator can stack right before a modal to negate the wish or ability itself.

我也不想去。

wǒ yě bù xiǎng qù

I don't want to go either. (informal) — 也 (scope) then 不 then the modal 想.

我明天不去了。

wǒ míngtiān bú qù le

I'm not going tomorrow after all. (informal) — time 明天 comes before 不.

我们不能跟他们一起去。

wǒmen bù néng gēn tāmen yìqǐ qù

We can't go with them. (neutral) — modal 不能 leads, ahead of the companion phrase.

💡

Picture 不/没 and modals as a single "predicate gate": everything the negation or modality covers passes through it, so the gate stands at the front of the predicate — right after the subject and time — with the coverb phrase and verb lined up behind it.

With 把 and 被

The same logic governs the 把 and 被 constructions: since 把/被 introduce the predicate, the negator or modal sits before 把/被, never between it and the verb. See negating 把 and using modals with it for the full pattern.

他没把作业做完。

tā méi bǎ zuòyè zuò wán

He didn't finish the homework. (neutral) — 没 before 把.

我不想把这件事告诉他。

wǒ bù xiǎng bǎ zhè jiàn shì gàosu tā

I don't want to tell him about this. (informal) — modal 不想 before 把.

Common Mistakes

1. Negating the verb instead of the coverb phrase. For "I don't eat at home (I eat out)," 不 must precede 在, not 吃.

❌ 我在家不吃饭。

Says something else — 'at home I don't eat'; for 'I don't eat at home' put 不 before 在.

✅ 我不在家吃饭。

wǒ bú zài jiā chī fàn

I don't eat at home.

2. Putting the negator after the modal for 'don't want to'. 不 negates the modal, so it comes in front of it.

❌ 我想不去。

Doesn't give 'I don't want to go' — 不 after the modal reads as 'I feel like not going'; to negate the wish itself, put 不 before it: 不想去.

✅ 我不想去。

wǒ bù xiǎng qù

I don't want to go.

3. Using 不 for a completed past action. A past event that didn't happen is negated with 没, not 不.

❌ 昨天他不跟我说。

Incorrect — a past non-event takes 没: 没跟我说.

✅ 昨天他没跟我说。

zuótiān tā méi gēn wǒ shuō

He didn't tell me yesterday.

4. Sliding the negator inside the 把 phrase. 没/不 must sit before 把, not after it.

❌ 我把作业没做完。

Incorrect — the negator belongs before 把: 没把作业做完.

✅ 我没把作业做完。

wǒ méi bǎ zuòyè zuò wán

I didn't finish the homework.

Key Takeaways

不/没 and modals sit after the subject, time, and 也/都, but before the coverb phrase and verb — they lead the whole predicate.
Because they take scope over what follows, moving 不 changes the meaning: 不在家吃 (don't eat at home) vs 在家不吃 (at home, don't eat).
To negate a wish or ability, the negator goes before the modal: 不想去, 不能去.
With 把/被, the negator or modal comes before 把/被 (没把…, 不想把…), never inside it.
Use 没 for a past non-event, 不 for the present, habitual, or future.
