"Who made the coffee?"
Translation:Kahveyi kim yaptı?
it is not wrong but it is very strange. if you ask who did something, the emphasis is on "WHO"; which means it (kim) should come before the verb. Your sentence puts stress on "kahveyi"
So this might be used if someone said "Selcen made the tea" - "OK, but who made the COFFEE?" I was thinking in terms of SOV word order, but I guess question words like "kim" or "ne" should always be right before the verb, right?
