How do you say nothing much in Italian?

Answer 1

Non so niente, but that's literally "I know nothing at all." ;-) If you mean you don't know anything about a specific issue, like "I don't know anything about it," you would say non ne so niente.

Niente di piu. It comes out nothing more but it is the same.

Answer 3

Non conosco bene l'italiano.

Answer 4
