Yes, absolutely. It just depends on the context. It can also mean sick as in ill (like poorly).
Oh, is that where the expression "he's got the boke" might come from??? A revolting expression - but a very expressive one, as it were.
I also wondered if that's where the Scots word "boak" came from.
Does bochd mean both poor in the sense of unfortunate, and also not having money?
Yes! It can also mean ill.
