Interesting. Unfortunately, I never learn Irish formally from my father, but I do recall some things he said, and I seem to remember that as characteristic of his accent. He'd be 90ish now if he were alive. Is the v pronunciation old-fashioned or more common among the elderly these days, do you know?
What does bhfuil mean? If ca bhfuil means where, why isn't that part of the table in the tips and notes section? Is where always ca bhfuil, or is it used because of what the sentence is about? (Sorry I don't have the proper punctuation over the letters. Is it punctuation?)
I'm not exactly sure, but I believe 'bhfuil' is a form of the verb 'bí' (the root being 'fuil', but here it is eclipsed), which means 'is'. so "ca bhfuil" means "where is," not just "where." I have gathered this from reading other comments in this section; it's very confusing. (I could be wrong, please correct me if I am)
