How to say "Can" in Gaelic?
That's a point, I hadn't thought about that other meaning in English. I don't think I'm in the habit of using "can" in that sense but I certainly recognise it.
There's quite a lot in Speaking Our Language about faodaidh / am faod / chan fhaod, as I recall.
ETA: In the sense of a question though, I certainly have used it like that. "Can I do that? Please Mum!"
I have been watching the old Can Seo programmes (and no that's not the answer, "Can" in Gaelic means "say", the title of the programme means "Say this"). But anyway, according to that, the Gaelic for "I can" is "‘S urrainn dhomh". Although the programme is 40 years old and spelling conventions have changed so I don't know how reliable that is.
My notes from the programme actually read
An urrainn dhut = Can you?
‘S urrainn dhomh = I can
Chan urrainn dhomh = I can’t
We've met "dhut" already as "for you", as in "Chan eil Irn Bru math dhut". I think I smell another beautiful prepositional pronoun "word baby" for us to learn in a later stage of the course.
