Chinese has two main words for “not”: 不 bù and 沒 méi没 méi. Which one you use depends on what comes after it: a noun, an adjective, or a verb.
一 At a Glance
Here’s the quick version:
+ Noun
+ Adjective
+ Verb
不 bù
❌
✅
✅ now / future / habits
沒没 méi
✅
❌
✅ past / hasn’t happened
二 With a Noun: 沒没
沒没 (有) + Noun
Before a noun, always use 沒 méi没 méi. It means “don’t have.” You can add 有 yǒu after 沒 méi没 méi and the meaning stays the same.
我沒没工作、沒没錢钱、沒没未來未来,只想當当米蟲米虫
No job, no money, no future. I just want to be a couch potato.
他沒没想法
He has no ideas.
我沒有没有時間时间
I don’t have time.
你沒有没有酒嗎吗?
You don’t have any alcohol?
Rice bug米蟲 mǐchóng米虫 mǐchóng (“rice bug”) is slang for someone who doesn’t study, work or train for a job. They just eat and sleep all day and let other people take care of them, like a little bug living in the rice jar. 🐛
三 With an Adjective: 不
不 + Adjective
Before an adjective, always use 不 bù. (Wondering why 不 sometimes has a 2nd tone? Here’s why.)
我不矮、不胖、不笨,也不醜丑
I’m not short, not fat, not stupid, and not ugly either.
那個那个不貴贵嗎吗?
Isn’t that one expensive?
沒没 + adjective?Sometimes you’ll hear 沒 méi没 méi + adjective. That’s because a verb has been dropped: 你沒變胖你没变胖 (“You didn’t get fat”) is often shortened to 你沒胖你没胖.
四 With a Verb: Choice vs. Fact
With verbs, both work, but they mean different things. 不 bù is about what someone doesn’t want or intend to do, or doesn’t do in general. 沒 méi没 méi states a fact: something didn’t happen. You can add 有 yǒu after 沒 méi没 méi here too.
不 bù · choice
我今天不吃晚飯晚饭
I’m not going to have dinner tonight. (My decision.)
沒没 méi · fact
我今天沒没吃晚飯晚饭
I didn’t have dinner tonight. (That’s just what happened.)
你昨天為什麼为什么不跟我說話说话
Why didn’t you talk to me yesterday?
I know you did it on purpose.
你昨天為什麼为什么沒没跟我說話说话
Why didn’t you talk to me yesterday?
I’m just asking what happened.
我不喝酒
I don’t drink.
A habit or a choice.
我沒没喝酒 = 我沒有没有喝酒
I didn’t drink.
A fact about what happened.
五 Not Yet: 還沒还没
還沒还没 + Verb
沒 méi没 méi has a “best friend”: 還沒 hái méi还没 hái méi, which means “not yet.” Use it for something that hasn’t happened yet but might.
我還沒还没喝酒
I haven’t had a drink yet.
她還沒还没死
She’s not dead yet.
She’s still alive!
我還还沒有没有寫写作業作业
I haven’t done my homework yet.
六 Common Mistakes
❌ 我不有時間时间
✅ 我沒有没有時間时间
有 yǒu is always negated with 沒 méi没 méi, never 不 bù.
❌ 他沒没高
✅ 他不高
Adjectives take 不 bù.
❌ 我昨天不去上課上课
✅ 我昨天沒没去上課上课
Yesterday is in the past, so it’s a fact that you didn’t go: 沒 méi没 méi.
❌ 我還还不吃飯饭
✅ 我還沒还没吃飯饭
“Not yet” is 還沒 hái méi还没 hái méi, not 還不.
