Do you know?

How do you indicate in French if you do not know something? No idea? Here are 5 ways to tell you’ve lost track.

Je n’en sais rien.
> I do not know. Literally: I know nothing about it.

Va savoir!
> Tell me (because I don’t know).

Tu me poses un colle.
> That is a difficult question. Literally: you put glue on me.

Aucune idea!
> No idea!

Je ne sais pas.
The most common way to say that you don’t know something should of course not be missing.
