Starting a sentence with "quoi"

Hi M,

Without the context it is hard to tell but I suspect based on the lesson content that it would be something like:

"Que veut Paul?" ("What does Paul want?")

You could say, "Paul veut quoi?"( in spoken French) but never at the begining of the sentence.

Normally you will hear Quoi ? , used in a single word as the interrogative pronoun What? (as in 'Pardon?')

In French you will say Quoi? or more politely Comment?

It is used also in some idiomatic expressions like:

Quoi de neuf? = Wha'ts new?

À quoi bon ...? = What's the point...?

Il n'y a pas de quoi = Don't mention it

Hope this helps!
