Which is correct: "he don't" or "he doesn't"? [closed]

Which one is correct in a sentence?

  • He don't
  • He doesn't

I guess "he doesn't" should be correct because he is third person singular but I've seen some people using do with he. Which one is correct?


He doesn't is correct, because it is the contraction of He does not.
He don't is incorrect, because it it the contraction of He do not.

Subject-Verb agreement requires that he goes with does.

He don't, however, is slang and certainly used in many places, but you would never see it in professional writing, because of Subject-Verb agreement.
