In conversation, would you hear " 'Bheil thu a' bruidhinn Gàidhlig?" or " 'Eil thu a' bruidhinn Gàidhlig?" more usually than "A bheil thu a' bruidhinn Gàidhlig?"
There's also a shift of register from the polite "leibh" to "thu". I take it that that's okay and not unintentional.
The tips say that "leibh" is used for everyone in this case, even small children.
I don't see why 'a bheil sibh a' bruidhinn gàidhlig' is wrong.
Why can this not be 'A bheil sibh a'bruidhinn Gaidhlig?'?
That will be accepted here :)
It is not accepted as of today
