不 or 没 – Declarative Sentences

不 (bù) in Declarative Sentences

不 (bù) Negates present actions

不 (bù) shows that an activity isn’t happening. It’s used to oppose an action you do not want to do.

Subject + 不 + Verb

  • 你吃早晚吗?
  • nǐ chī zǎowǎn ma?
  • Do you eat breakfast?
  • 我不吃。
  • wǒ bù chī.
  • No I don’t.

不 (bù) Negates habitual actions

不 (bù) can be used to oppose habitual actions, which indicates something you are not used to doing.

Subject + 不 + Verb + Object 

  • 我不吃肉。
  • wǒ bù chī ròu
  • I don’t eat meat.
  • 你们都不喝酒吗?
  • nǐmen dōu bù hējiǔ ma
  • Don’t you all drink alcohol?

不 (bù) Negates future actions

不 (bù) is used to negate an action that you do not intend to do. 

Subject + 不 + Verb

  • lǎobǎn míngtiān bù lái.
  • The boss won’t come tomorrow.
  • 我知道这个周末不下雨。
  • wǒ zhīdào zhège zhōumò bùxià yǔ
  • I know it won’t rain this weekend.

没 (méi) in Declarative Sentences

没 (méi) Negates Past Actions (can be replaced by 没有)

没 (méi) is used to refute/deny actions that occurred in the past.

Subject + 没 + Verb + Object

  • 我昨天没喝酒。
  • wǒ zuótiān méi hējiǔ.
  • I didn’t drink alcohol yesterday
  • 他昨天没打电话给我。
  • tā zuótiān méi dǎ diànhuà gěi wǒ

没 (méi) can say something has not happened yet

Subject + 没 + Verb + Object

  • 他们吃完饭以后没付钱。
  • tāmen chī wán fàn yǐhòu méi fù qián
  • They didn’t pay after eating.
  • 妈妈没做晚饭。
  • māmā méi zuò wǎnfàn
  • Mom didn’t cook dinner.

没 (méi) can use to indicate something has not been experienced

“过” has to be used after the verb.

Subject + 没 + Verb + 过 + Object

  • 我没吃过中国菜。
  • wǒ méi chīguò zhōngguó cài
  • I have never eaten Chinese food

Subject + (从来) 没 + 去 + 过 + place

  • 我(从来)没去过中国。
  • wǒ (cónglái) méi qùguò zhōngguó
  • I have never (ever) been to China

More examples:

When using 不(bù), it means that you normally “do not” eat breakfast.

When using 没(méi), however, the meaning changes to saying you “did not” eat breakfast, implying that you’re talking about “what you did not do today”.

我不喝酒。(habitual actions) 

我明天不喝酒。(√) 

我明天没喝酒。(×)

我没喝酒。(negate past actions)

我昨天不喝酒。(×) 

我昨天没喝酒。(√)

BONUS: 不 + adjective

不 (bù) is used with adjectives. When it comes to a simple negation of an adjective, use 不 (bù).

Subject + 不 + Adjective

  • 我不饿。  
  • wǒ bù è
  • I am not hungry.
  • 你不胖。  
  • nǐ bù pàng
  • You are not fat.
  • 今天不冷。
  • jīntiān bù lěng
  • It is not cold today.

The negation of adjectives is generally used “不”, but sometimes you can hear 没 + adjective, which implies that the state has not changed.

  • 我不胖。
  • wǒ bù pàng
  • I am not fat.
  • 我没胖。
  • wǒ méi pàng
  • I have not gained weight.

不 or 没 – Interrogative Sentences

Question with 没 (méi)

As mentioned previously, 没 is used with the past tense, as well as to describe that something has not yet been experienced or didn’t happen yet.

Subject + Verb + 没 + Verb + Obj?

  • 昨天你吃没吃四川菜?
  • zuótiān nǐ chī méi chī sìchuān cài?
  • Did you eat Sichuan food yesterday?
  • 上个月你们去没去旅游?
  • shàng gè yuè nǐmen qù méi qù lǚyóu?
  • Did you go travel last month?

Subject + Verb + 没 + Verb + 过 + Object?

  • 你吃没吃过中国菜?
  • nǐ chī méi chīguò zhōngguó cài?
  • Have you ever tried Chinese food?

Subject + 去 + 没 + 去 + 过 + place?

  • 去没去过中国?
  • nǐ qù méi qùguò zhōngguó?
  • Have you ever been to China?

Question with 不 (bù) 

As mentioned previously, 不 is used for present or habit actions, or future actions. It is the same in the interrogative form:

Subject + Verb + 不 + Verb + Object?

  • 你吃不吃四川菜?
  • nǐ chī bù chī sìchuān cài
  • Do you eat Sichuan food?
  • Present or habit actions
  • 你们周末上不上班?
  • nǐmen zhōumò shàng bù shàngbān
  • Will you go to work this weekend?
  • Future actions

不 (bù) can also be used to form tag questions. 

Sentence,好+不+好 / 对+不+对?

Tag questions are used to seek approval or acceptance for a statement, very similar to the English “OK?” or “right?”

You can’t use 没 (méi) for this.

Examples:

  • 我们去游泳,好没好?(×)
  • 我们去游泳,好不好?(√)
  • 你们是好朋友,对没对?(×)
  • 你们是好朋友,对不对?(√)

Chinese Grammar – 不、没 and 是、有、在

Only 不 (bù) negates 是 (shì)

不 (bù) can be used to reverse the verb 是 (shì), which is the word for ‘to be’ changing the meaning “to not be”. 

Subject + 不 + 是 + predictive

  • 我不是医生。(present)
  • wǒ bùshì yīshēng
  • I am not a doctor
  • 我以前不是老师。(past)
  • wǒ yǐqián bùshì lǎoshī
  • I was not a teacher before
  • 今天不是星期一。
  • jīntiān bùshì xīngqí yī
  • Today is not Monday
  • 昨天不是8月15号。
  • zuótiān bùshì 8 yuè 15 hào
  • Yesterday was not August 15th

Only 没 (méi) negates 有 (yǒu)

没 (méi) can be used to negate the verb 有 (yǒu) (to have) to mean “do not have”. 

Subject + 没 + 有 + Object

  • 我没有书。
  • wǒ méiyǒu shū.
  • I don’t have books.
  • 我没有女朋友。
  • wǒ méiyǒu nǚ péngyǒu.
  • I don’t have a girlfriend.

Both 不 (bù) and 没 (méi) can negate 在 (zài)

And they have the same meaning (to be in/at)!

昨天我没在家。= 昨天我不在家。

zuótiān wǒ méi zàijiā = zuótiān wǒ bù zàijiā.

I was not home yesterday.

Examples:

  • 我不是学生。(√)
  • 我没是学生。(×)
  • 我不有钱。(×)
  • 我没有钱。(√)

Note: “没有 + verb + Object” and “没 + 有 + Object”

  • Subject + 没有 + Verb + Object
  • 我没有喝酒。
  • wǒ méiyǒu hējiǔ.
  • I didn’t drink wine yesterday.
  • 没有 = 没
  • Subject + 没 + 有 + Object
  • 我没有酒。
  • wǒ méiyǒu jiǔ.
  • I don’t have wine.
  • 没 + 有 (verb)

In the above example, “有” can be omitted and the meaning doesn’t change.

  • 我没有喝酒。= 我没喝酒。
  • wǒ méiyǒu hējiǔ = wǒ méi hējiǔ.
  • 我没有酒。= 我没酒。
  • wǒ méiyǒu jiǔ.= wǒ méi jiǔ.

Making Comparisons with 不 and 没

不 (bù) can be used to make simple comparisons such as “not as… as…”:

Noun 1 + 不比 / 不如 + Noun 2 + Adjective

  • 我的手机不比他的手机贵。
  • wǒ de shǒujī bùbǐ tā de shǒujī guì.
  • My phone is not as expensive as his phone.
  • 我的书不如他的书多。
  • wǒ de shū bùrú tā de shū duō.
  • My books are not as many as his.

没 (méi) or 没有 (méiyǒu) can also be used to make simple comparisons such as “not as… as…”:

Noun 1 + 没有 + Noun 2 + Adjective

  • 你没有我高。
  • nǐ méiyǒu wǒ gāo.
  • You are not as tall as me.
  • 上海的冬天没有北京的冬天冷。
  • shànghǎi de dōngtiān méiyǒu běijīng de dōngtiān lěng.
  • The winter in Shanghai is not as cold as the winter in Beijing.

Collocations of 不 and 没

It’s best to accumulate these one by one.

没 (méi)

不 (bù) 

可不 (是)

When we use 可不 or 可不是 as an independent expression, even with negative word 不, it means “Exactly!”.

  • A:地铁上的人真多!
  • dìtiě shàng de rén zhēn duō!
  • There are so many people on the subway!
  • B:可不 (是) !
  • kěbù (shì)!
  • That’s so true!

不 and 没 expressing affirmative

不 and 没 usually indicate negative expressions, which makes it confusing, since they can also represent affirmative expressions. 

好容易 and 好不容易 (very easy and very not easy)

容易 (rónɡyì) means “easy”, and 好 (hǎo) here is used as an adverb which means “very“.

In this sense, these two phrases are expressing two opposite meanings. However, they are both used before verbs to indicate how difficult it is to do something.

I finally passed the HSK test for level 6:

We finally climbed to the mountain top:

差点 and 差点没 (almost and almost not)

When they are followed by things that people want to happen, both 差点 (chàdiǎn) and 差点没 (chàdiǎn méi) express the opposite meanings for the following verbs.

差点: negative ≠ 差点没: affirmative

I almost passed the HSK test for level 6: 我差点通过了HSK六级考试。(wǒ chàdiǎn tōnɡɡuòle liùjí kǎoshì.)

Even though there’s no negative word in this example, it still means “I didn’t pass the test”.

I just barely passed the HSK test for level 6.  我差点没通过HSK六级考试. (wǒ chàdiǎn méi tōnɡɡuò liùjí kǎoshì.)

There’s a negative word 没 in this example, but it means “I passed the test”.


When they are followed by things that people don’t want to happen, both 差点 (chàdiǎn) and 差点没 (chàdiǎn méi) mean that thing didn’t happen.

差点 = 差点没: negative

I almost broke the cup:

Both sentences mean “I didn’t break the cup”.

My wallet almost got stolen:

Both sentences mean “My wallet wasn’t stolen”.

First of all, Chinese is a SVO language (Subject – Verb – Object), like many European languages and English. Add to that a negation word or a question word, and you can now express yourself in a lot of new different ways!
