ain't no mountain high enough
there is a song named ain't no mountain high enough. But why "ain´t" ? Isn´t "ain´t" the short form of " has not, have not, is not , am not, are not"?
Hasn´t no mountain high enough?? Is it the correct way to say?

Answer

"Ain't" is a lazy/slang word, meaning "isn't". It is often heard, but shouldn't be written.

Answer

It means "there is no mountain high enough"

Answer

"Ain't no mountain" = there isn't any mountain (in regular grammar).

So-called "bad" grammar sounds rather cool in a pop song. Well, at least the kids love it.

There's an old comedy sketch called "Elderly Man River", where the singer is corrected every time he sings something "wrong" in the classic song, "Ol' Man River." It's worth looking up. :)
