"Who is your lawyer?"
Translation:Cé hé do dhlíodóir?
atá is a form of the verb bí. This would be a copular question, so you'd need hé (or hí) after cé. It literally translates as "Who is it, your lawyer?"
Would cé hé or cé hí be used for all copular single person "Who is..." questions, then?
My bad. I misread it as just "who is..." questions.
For copular ones, yes. At least in the standard. In Connacht Irish, you'll see Cérb é for 'Who is he' (Cérbh é in the past).
I don't we've actually learned anything about hé yet. And yet here it is in review.
That’s how DL works. It by and by introduces new material mixed into stuff already learned so that you can draw your own conclusions about what’s going on. Not every single aspect of complex grammar can be dealt with in the sparse notes that DL offers. They give you the very basics; the sentences provide a variety of usages.
Apart from that, we have encountered the h affixed between to “colliding” vowels previously, e.g. Dé hAoine. So this is only a new variation of an already learned mechanism.
iad is plural, dlíodóir is singular.
Cé hé do dhlíodóir? - asking one person about one lawyer.
Cé hé bhur ndlíodóir? - asking more than one person about their shared lawyer (just one lawyer).
Cé hiad bhur ndlíodóirí? - asking more than one person about multiple lawyers. You might also write that as Cé hiad bhur gcuid dlíodóirí?
Sexist correction! I put "cé hí" because a lawyer could be female... or do we have to say "cé hé" because the word dlíodóir is masculine? It seems weird to say "Is é Clíona mo dhlíodóir" though!
If you know for a fact that the lawyer is a woman, you could indeed say cé hí do dhlíodóir?, but you are asking for the name of a lawyer that you have already seen.
But where the gender of the person can't be assumed, cé hé is the default.
If you feel aggrieved by the gendered nature of such constructions, you can work around them by asking "who's is representing you?" - cé atá ag déanamh ionadaíochta duit? or maybe even cé atá i do dhlíodóir? (though that might imply that your lawyer is new or temporary).
Is í Sinéad mo dhlíodóir is the correct form for a response (at least if you allow for conventional gender naming conventions), even if the question asked is cé hé).
