ain't [eɪnt] Not standard contraction of : am not, is not, are not, have not, or has not I ain't seen it

"Ain't" is not a part of standard english. However, in some dialects, it is used a lot. You hear it a lot in rap music. It means the following : 1. am not; are not; is not. e.g. I ain't happy You ain't gonna make my angry They ain't happy It ain't good 2. have not; has not; do not; does not; did not. e.g. I ain't seen it He ain't done it Used also as an interrogative : I am Good ! ain't I ? They are happy ! ain't they ?

I am not happy I ain´t happy

"ain't" actually that is "are not or am not"
