"He has a girl."
Translation:Tá cailín aige.
Note: This would mean more "he has a girlfriend" than "he has a daughter".
Huh. So if you were to say the same thing "he has a girl" but mean his daughter, is there a difference in how to say it?
You would say "he has a daughter". Tá cailín aici means that he has, in his possession, a girl. It can also mean he has a girlfriend (similar to how Tá bean aige can mean "he has a wife"). For daughter, iníon is used.
Anybody have a good way of remembering which conjugation of "have" belongs with which pronoun?
Write, not type, each form with its English equivalent multiple times. “Muscle memory” will increase your retention.
