to want vs. to feel like

In our level one class we were discussing avoir envie de and whether it means "to want" or "to feel like."

Sooo I asked my fiance (a native French speaker) about avoir envie de and he said it does mean "to want."

Avoir UNE envie de means "to feel like."

So "Il a envie d'une moto" makes sense and so does "Avez-vous envie d'un crayon ou d'un stylo."

Here's what he said the difference is:

Je n'ai pas une envie de travailler - I don't feel like working

Je n'ai pas envie de travailler - I don't want to work
