I understand now that:
In French there is no “like” as in English. Something doesn’t smell like chocolate, it just “smells chocolate”.
So, you would say: Ça sent le chocolat
But how would you say "Who smells chocolate?"
Qui sent le chocolat ?
Whereas Qu'est-ce qui sent le chocolat is the longer way of saying "What smells like chocolate"
Is this correct?
Or would you have to say something like: qui peut sentir le chocolat ?
