What

interrogative pronoun (3rd person singular inanimate), interrogative determiner / adjective.

Interrogative pronoun

In both English and French, it is considered quite lax to say:

• You want what? Tu veux quoi?

But I am sure that both anglophones and francophones find these phrasings perfectly functional. Nevertheless, normatively it does seem to me that the English proposition is considered "wrong" despite its relative frequence in natural speech. Of course in school we are taught to say:

What do you want? Qu'est-ce que tu veux?

keskə and wədə. Kesk'il veut. Wədəz he want?
