The house of Babel

There are normally two ways to deny in Chinese.
bù(不) and méi(没)

bù(不) (From nciku)
* 1. ( used before verbs , adjectives , and other adverbs ; never before 有) not ; won’t ; not want to
* 2. ( used before certain nouns to form an adjective ) un- ; in- ;
* 3. ( used by itself or with a particle in responses ) not so; no

méi(没) (From nciku)
* 1. not have ; there is not ; be without
* 2. be not so. .. as
* 3. less than ; not more than
* 4. have not or did not

For example,
我不做。(I do not want to do it)
我没做。(I did not do it)

I was thinking what grammar is. Of course, first we have languages, then we have grammar. Grammar is just something to describe the language. For native speaker, we learn how to speak the language before we know the grammar. For foreign speaker, first we learn the grammar, then we speak rightly.
