Where people usually slip

Three common mistakes, all about using the wrong negative next to have / has.

You don't need do / does: not I don't have seen the film, but I haven't seen the film.

The third person takes hasn't, not haven't: not Anna haven't called, but Anna hasn't called.

After haven't / hasn't you need the third form: not I haven't saw Tom, but I haven't seen Tom.

  • I, you, we, theyI haven't seen the film.
  • he, she, a nameAnna hasn't called.
  • without do / doesnot I don't have seen
