Mandarin Negation: 不 (bù) vs 没 (méi)
English gets by with one "not". Mandarin has two, and they split the work cleanly: (bù) negates what is true now, what will be, what is habitual, and adjectives; (méi) negates what did not happen. And (yǒu, to have) only ever takes .
Quick check
Three quick questions on what you have just read. The full practice is further down.
Pick the right one
0/3Pick the right negator: 不 for now, the future, habits and adjectives; 没 for what did not happen, and for 有.
我去。 (I am not going - a decision about the future)
wǒ ___ qù 。 (I am not going - a decision about the future)
他还来。 (he has not come yet)
tā hái ___ lái 。 (he has not come yet)
我有咖啡。 (I have no coffee)
wǒ ___ yǒu kā fēi 。 (I have no coffee)
The two negators at a glance
The colours stay the same all page long: (bù) in one colour, (méi) in the other.
| Negator | Pinyin | Negates |
|---|---|---|
| bù | now, the future, habits, adjectives, | |
| méi | what did not happen, and |
One verb, (qù, to go), shows the whole system in miniature:
| Hanzi | Pinyin | English |
|---|---|---|
。 | Wǒ bú qù. | I am not going / I will not go |
。 | Wǒ méi qù. | I did not go |
(wǒ bú qù) is about now or the future: I am not going, I refuse to go. (wǒ méi qù) is about the past: the going did not happen.
不 (bù): the present, the future, habits, and adjectives
(bù) goes directly in front of the verb or adjective, and nothing else in the sentence moves. If the English negative is "don't", "won't", "isn't" or "not + adjective", you want .
| Hanzi | Pinyin | English |
|---|---|---|
。 | Wǒ míngtiān bú qù. | I'm not going tomorrow |
。 | Wǒ bù zhīdào. | I don't know |
。 | Wǒ bù xǐhuan zhège. | I don't like this one |
。 | Tā bú shì wǒ xiānsheng. | He isn't my husband |
。 | Zhège bù hǎo. | This one isn't good |
Three of those rows are rules in their own right:
- (shì) always takes , never
:。(Tā bú shì lǎoshī.), he is not a teacher. See the copula 是. - Adjectives take directly. There is no "is" to negate, because the adjective already means "to be good":
。(Zhège bù hǎo.), this one isn't good. - Wanting and habits are states, so they take even in the past:
。(Tā zuótiān bù xiǎng qù.), he didn't want to go yesterday.
没 (méi): what did not happen
(méi) negates actions that did not take place. If the English negative is "didn't" or "hasn't", you want .
| Hanzi | Pinyin | English |
|---|---|---|
。 | Tā méi lái. | He didn't come |
。 | Tā méi shuō shénme. | She didn't say anything |
。 | Tā méi gàosu wǒ. | He didn't tell me |
。 | Tā hái méi lái. | He hasn't come yet |
Notice what is missing from every row: any past marking on the verb. does the "did not" work by itself, and the verb stays in its dictionary form. That is why a plain "didn't" takes no (le): 。 (Wǒ méi qù.), never (wǒ méi qù le).
The full form (méiyǒu) also negates a verb, and means exactly the same: 。 (Wǒ méiyǒu qù.) - I didn't go. Short is the everyday choice in speech.
With (hái, still), says something has not happened yet, and this works with an adjective too, because becoming better is a change that did not happen: 。 (Tā hái méi hǎo.) - He isn't better yet.
有 (yǒu) only ever takes 没
(yǒu, to have / there is) never takes . Its negative is always (méi yǒu), in every tense and every context.
| Hanzi | Pinyin | English |
|---|---|---|
。 | Wǒ méi yǒu kāfēi. | I have no coffee |
。 | Zhèlǐ méi yǒu rén. | There's nobody here |
。 | Wǒ míngtiān méi yǒu shíjiān. | I'm not free tomorrow |
The full bowl: 有 yǒu, there is some. The empty one: 没有 méi yǒu, there is none left. Never 不有.
(bù yǒu) does not exist: not rare, not formal, not regional. When shows up, the choice is already made for you. In speech, often shortens to bare before a noun: 。 (Wǒ méi shì.) - I'm fine, nothing's wrong. The full story of is in possession with 有.
The tone change: bù becomes bú before a fourth tone
is a fourth-tone syllable, bù. But when the syllable after it is also fourth tone, is said with a rise, as a second tone: bú. The character never changes.
| Written | Said | Why |
|---|---|---|
| bú shì | shì is fourth tone | |
| bú qù | qù is fourth tone | |
| bú yào | yào is fourth tone | |
| bù hǎo | hǎo is third tone | |
| bù lái | lái is second tone | |
| bù shuō | shuō is first tone |
This is special to and (yī): other fourth tones keep their tone before a fourth tone, so is zàijiàn. (méi) has no tone change at all. The rule is in tone pairs.
Mistakes English speakers make
| Wrong | Right | Why |
|---|---|---|
。 | 。 | (yǒu) only takes (méi) |
。 | 。 | The future takes (bù) |
。 | 。 | (méi) already says it didn't happen |
。 | 。 | A plain adjective takes (bù) |
。 | 。 | (shì) only takes (bù) |
Most of these come from treating (bù) as "the" word for not. Ask one question first: did something fail to happen? If yes, (méi); if not, (bù).
(bù) and (méi) are on the AQA GCSE Chinese specification at Foundation and Higher tier.
The cheatsheet
| Situation | Negator | Example |
|---|---|---|
| Now or future | 。 (wǒ bú qù) | |
| Habit, liking | 。 (wǒ bù xǐhuan zhège) | |
| Adjective | 。 (zhège bù hǎo) | |
| With | 。 (tā bú shì lǎoshī) | |
| Didn't happen | 。 (tā méi lái) | |
| With | 。 (wǒ méi yǒu kāfēi) |
Going further
- The copula 是 for
(shì) and(bú shì). - Possession with 有 for
(yǒu),(méi yǒu) and "there is". - 了 (le) and the aspect markers for why
(le) disappears after(méi). - 也 and 都 for
(yě bù), not ... either.
