Revision as of 07:21, 26 November 2012

Both 不（bù) and 没 (méi) can be placed in front of a verb or adjective to negate its meaning. However, 不 and 没 are not usually interchangeable, so it's important to learn when you must use 不 as opposed to 没, and vice versa.

不 is for negating in the present and future

不 is generally used to negate an action that you do not want to do or do not intend to do (in the future). So expressing things like "I don't want to go" or "I'm not going" would be uses of 不.

Structure

Subject + 不 + Verb

Examples

Whether it's "don't wanna do it" or "not gonna do it," use 不:

  • 我 今天 晚上 不 吃 饭。
  • 我 今天 晚上 不 想 吃 饭。
  • 他 不 去 公园。
  • 他 不 要 去 公园。

不 is used to negate habitual actions

不 can be used to negate habitual actions. This is simply done by placing 不 in front of the verb.

  • 我 不 吃 肉。
  • 我 不 看 电视。
  • 我 不 喝 酒。
  • 我 没 喝 酒。

Please note that, while it is grammatically correct to use 没 in situations like these, 没 does not negate any habitual actions. The 没 sentence used above translates into "I didn't drink alcohol" as opposed to "I don't drink alcohol".

不 is normally used with adjectives

When it comes to a simple negation of an adjective (e.g. "not Adj"), use 不.

Structure

不 + Adj

Examples

  • 我 不 高兴。
  • 她 不 漂亮。
  • 你的 女朋友 不 难看。
  • 我们 不 饿。
  • 你 不 聪明。

不 is used to ask questions

There a couple ways to use 不 to ask questions. One such way is through positive-negative questions. This is done by stating a verb and then immediately repeating that verb in a negative state (with 不):

  • 你 是 不 是 我 的 老师。
  • 今天 你 来 不 来？
  • 你 喜 不 喜欢 吃 中国菜。

不 can also be used to form tag questions. Tag questions use the positive-negative question form, but are placed at the end of the sentence. 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 for this.

  • 我们 去 吃饭，好 不 好？
  • 你 是 我的 同学，对 不 对？
  • 我们 喝 水，好 没 好。
  • 你 得 上 课，对 没 对。


See the grammar page for Positive negative questions here: http://resources.allsetlearning.com/chinese/grammar/Positive_negative_questions

See the grammar page for Tag questions here: http://resources.allsetlearning.com/chinese/grammar/Tag_questions_with_%22bu%22

不 is used almost exclusively with some verbs

  • 明天 我 不 在 家。
  • 上周 我 不 和 我 的 朋友 在 一起。

不: other uses

不 is a very common word in the Chinese language and an integral part of many grammar points. See those grammar points here: http://resources.allsetlearning.com/chinese/grammar/%E4%B8%8D

没: general use

“没”用于描述过去，说明动作没有发生。很多时候和“有”一起用，意思和用法不变。 没 is used to describe actions in the past or illustrate that an action hasn’t happened yet.

Structure

Subject + 没（有）+ V.

Examples

  • 昨天 晚上 我 没 吃 饭。
  • 他 没有 去 公园。
  • 明天 我 没 在 家。
  • 上周 我 没 和 我 的 朋友 在 一起。

See the grammar page here: http://resources.allsetlearning.com/chinese/grammar/Standard_negation_with_%22bu%22

没 is used to negate 有

没 can be used to negate the verb 有 to mean "do not have". You can only use 没 to convey this meaning. It is grammatically incorrect to use 不.

  • 我 没有 钱。
  • 我 不有 钱。

See the grammar page here: http://resources.allsetlearning.com/chinese/grammar/Negation_of_%22you%22

There are times when you can leave out 有 entirely while still expressing 没有. The best example of this is 没办法.

  • 我 没 办法。
  • 我 没有 办法。

Both of these statements have the same meaning, but the use of 没 is slightly different.

See the grammar page here: http://resources.allsetlearning.com/chinese/grammar/Inability_with_%22mei_banfa%22

没 is used to make comparisons

没有 can be used to make simple comparisons.

  • 我 的 钱 没有 他 的 钱 多。
  • 你 的 钱 不有 他 的 钱 多。
  • 你 没有 我 高兴。
  • 你 不有 我 高兴。

See the grammar page here: http://resources.allsetlearning.com/chinese/grammar/Basic_comparisons_with_%22meiyou%22

没 is used to negate past actions

没 and 没有 can both be used to negate actions that occurred in the past.

  • 他 没有 打 电话 给 我。
  • 他 没有 上课。
  • 我 昨天 没 喝 葡萄酒。
  • 我 昨天 不 喝 葡萄酒 。

There are a few things worth noting in these examples. For one, it is still grammatically correct to leave out the 有 in the sentences using 没有. Also, the sentence using 不 would be grammatically correct, if not for the 昨天 ("yesterday") telling us that it is definitely the past we're talking about. but 不 does not negate past actions. That incorrect sentence using 不 would translate into "I don't drink wine yesterday" as opposed to "I didn't drink wine yesterday."
