For example, how would I say "Where can i buy milk?"

Not sure, but my first guess would be Cathain a féidir liom bainne a cheannaigh?

That just feels off to me though. What is the correct way of saying this, and what alternatives are their?

'Cathain' means 'when' in Munster, which might be why it feels off, as well as cheannaigh needs to be cheannach(t).

I'd say something like 'Cá bhfuil (cáil) mé in ann bainne a cheannach(t)'? With the copula, I believe it'd be 'Cár féidir liom bainne a cheannacht?'

Arrrggh!!!

Can't believe I put Cathain instead of cá bhfuil!!!


Is cáil essentially a contraction of sorts for ca bhfuil?

And is the optional "t" at the end of cheannach(t) a dialectal thing?

Deireann muid "ceannacht" i dTír Chonaill, níl mé cinnte an n-úsáidtear ins na canamhaintí eile é.

"Ceannacht" i gConamara freisin.

Cá, cén áit, canad, cá háit, ...



Yes, cá bhfuil > cáil
