This is a simple one.
- Could you tell me what "Carbonara" is?
Now. The question is: Which intonation should be used? Is it a yes/no question or a wh-question? -It is a polite request for information, so obviously I am not expecting a "yes/no" answer. But it functions as a "what-question", right? I am not sure if maybe the grammar requires me to consider it as a yes/no question.
I am a bit confused. Although, I am having a feeling that the answer is really simple and that I am currently having a blonde-moment. Please help me get rid of my doubt!
