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.
> Tell me (because I don’t know).
Tu me poses un colle.
> That is a difficult question. Literally: you put glue on me.
> No idea!
Je ne sais pas.
The most common way to say that you don’t know something should of course not be missing.
