i know its a very absurd question. But i dunno its answer.
Question: What does Ain't mean?
is it : "is not" or "has not" or what?
I always thought "ain't" was colloquial and therefore not proper or correct English.
Hmmmm I still do!
"is not" - He ain't here.
"are not" - They ain't neither.
"has not" - He ain't been here in days.
"have not" - Ain't you heard a thing I said?
