How the contraction "ain't" is used?
Hello!
I have read the contraction "ain't" in a song and I know its translation, but I don't know which tense corresponds.
The sentence is: "But ain't done much healing" (Hello!, song of Adele)
I can understand that corresponds with the present perfect but I had never seen before.
It can be used with other tenses?
Thank you so much

Question

Answer

Ain't is improper English.  It is a contraction of "am not".  Although, it is also used in place of "is not", "are not" or "have not".  In the above sentence, it'd translate best to:  But I have not done much healing ...  See https://en.wiktionary.org/wiki/ain%27t
