I searched the forum and couldn't find any previous mentions of
this question, so forgive me if I'm repeating another topic
somewhere. I have been wondering for a while what the difference
is between "mo" and "a." I've seen both words used to mean "my,"
but I haven't yet figured out when you're supposed to use each
of them. If someone could please explain it to me, I would be
very grateful. I'm just a casual learner of the Irish language,
but I'm very curious to know what the rule is to this. thanks in
advance for any help! I am presuming that you mean in the
context of 'Mo Mhamaí' and 'A Mhamaí'. 'Mo Mhamaí' is used when
you are referring to her. 'A Mhamaí' is used when you are
addressing her directly. 'Chuaigh Áine agus mo Mhamaí go dtí an
siopa.' 'Áine and (my) Mammy went to the shop.' 'A Mhamaí, ba
mhaith liom dul go dtí an siopa leat.' 'Mammy, I'd like to go to
the shop with you.' There are much more knowledgeable people
around there than I and they'll have all kinds of weird and
wonderful grammar terms
