I was just wondering what "Do you have a boyfriend" translates too as I know the grammer for "I have a boyfriend". I can't even find the answer on Google.
Is it An bhfuil buachaill ?
I would think the correct phrase would be, "An bhfuil buachaill agat?" The idiom "to have" is expressed using the preposition "ag" (meaning at) and the prepositional pronouns constructed from it are typically used unless a defined person is indicated.
