Chinese grammar: Negation of past actions mei/meiyou没和没有

Use 没有 (méiyǒu) to negate past actions (to say that someone didn’t do something, or something didn’t happen).


Usually verbs can be negated with 不, but that construction is used for habitual or present actions. If the verb is about an action in the past, though, 没有 should be used:

Subject + 没有 +  Verb


Wǒ méiyǒu hē nǐ de píjiǔ.
我 没有 喝 你的 啤酒。
I didn’t drink your beer.

Note that you can shorten 没有 to just 没:

Wǒ méi qù.
我 没 去。
I didn’t go.

Remember that 了 is not used with 没有. 了 marks completed actions, whilst 没有 is used for actions that didn’t happen. These two don’t work together. This is a very common mistake for Chinese beginners, so be sure to be attentive to it.
