Question on an example

Question

Julie a vraiment envie de chocolat = May I ask why this does not read as du chocolat? Since it's le chocolat? Or is it because in this context, this refers to some chocolat - but even then I didn't understand why du gets dropped - wouldn't it be envie du chocolat?

Accepted Answer

Elle a envie de chocolat. -- She wants chocolate. This refers to some general chocolate, not a specific kind or piece of chocolate.Elle a envie du chololat que tu as acheté hier. -- She wants the chocolate that you bought yesterday.

Answer

I think it would be helpful if the explanation that follows that example flagged up that distinction. Currently it simply says:

"Note that de becomes du / de la / de l' / des depending on the gender and number of the noun following it (e.g. of the)."
