As far as I understand, "ain't" can mean either "isn't" (ain't no sunshine) or "hasn't" (you ain't seen nothing yet).

Are there any rules when "ain't" is used? Does it have a different meaning than "isn't" or "hasn't"?

Edit: Maybe asking for rules was not the best idea. A better question would have been: when do you use "ain't" instead of "isn't"/"hasn't"?

Ain't is used as a regular negated form of be or have, and supposedly sometimes do:

  • I ain't no tractor. = I am not a tractor.

  • I ain't got no tractor. = I haven't got any tractor.

It's also used like there isn't, by common omission of there from there ain't.

  • Ain't no tractor here. = There isn't any tractor here.

And in case you hadn't guessed, dialects that use ain't stereotypically use negative concord as well.

    It doesn't always have to be used with negative concord: "It ain't that kind of party." "I ain't sure which one I want." "Ain't that a shame." And so on.

I was taught that "ain't" is a contraction of "am not." Its wide misuse has caused it to be considered slang.


In response to your edit, the best time to use ain't is to catch attention or to gain emphasis.
