Is dochtúir a mac.
(Some say "doctúir" or "doctar", though, but since it looks like you want to write in the CO, you should use "dochtúir").

***i'm not 100% about any of these, if someone could look at them and correct them, that would be great****

quote:

Is é a n-athair an fear sin.

According to Graiméar Gaeilge na mBráithre Críostaí^*) the noun with a demonstrative adjective (sin) should be first:
Is é an fear sin a n-athair

quote:

2)is that your sister? yes.
an í sin do dheirfiúr? sea

No, "ea" in "sea" is something indefinite.
But both "í sin" and "do dheirfiúr" is definite.
So the answer should be rather Is í sin. or Sin í.

But in 3) "sea" is right:

quote:

3)is she a lecturer? yes, she is a good lecturer.
an léachtóir í? sea, is leachtóir maith í

Right. But I'd rather say Sea, is maith an leachtóir í. (to emphasize that she's a good lecturer, because "sea" already answered the question)

quote:

4)is that her name? it is a beautiful name.
an í sin a ainm? is ainm go halainn í

I'm not sure but "ainm" is masculine, "focal" is masculine, so rather é sin instead of í sin (and "a hainm" = her name):
An é sin a hainm?
And "go" is wrong here:
Is ainm álainn í

quote:

5)that horse belongs to martin, it is a very strong horse.
is é le martin an capall sin, is capall iontach láidír é

Is le Martin an capall sin, ... (without é)

Lars

See, this is why I hold back and let others do the corrections. Ainm is actually feminine in the dialect I learned, so An í sin a hainm? looks fine to me. On the other hand, I'd follow that up with Ainm alainn is ea í or Is alainn an ainm í and not Is ainm álainn í/é even though I know the latter is correct CO. More fodder for our discussion of dialect differences, I guess.

quote:

I'd follow that up with Ainm álainn is ea í or Is álainn an ainm í and not Is ainm álainn í/é even though I know the latter is correct CO.

As far as I know, both your forms are also correct under CO rules, although the version Lars gave might be the preferred one. They have nuances of meaning, though.

Sea, is maith an leachtóir í.

léachtóir
