"The man has shirts."
Translation:Tá léinte ag an bhfear.
Ulster Irish prefers lenition; the other dialects prefer eclipsis. The Caighdeán allows either.
To be fair, from using the Duolingo app myself to start the course, I didn't learn until recently that the web version is more comprehensive and that there were even notes sections at all. Am really appreciating those who have taken the time to chime in on the threads with links, more directions, etc.!
aige is a prepositional pronoun - a combination of the preposition ag and the pronoun é. There is no pronoun in "the man has a shirt".
Tá léine aige - "he has a shirt"
Tá léine ag an bhfear - "the man has a shirt"
