How do you say no not in french?

There are a few ways to say "no" in French, depending on the context and the level of formality:

Formal:

* Non. (This is the most common and neutral way to say no.)

* Pas du tout. (This means "not at all" and emphasizes the negative.)

Informal:

* Non. (This is also the most common and neutral way to say no in informal situations.)

* Nan. (This is a more casual and familiar way to say no.)

* Nope. (This is an informal way to say no borrowed from English.)

Other options:

* Je ne sais pas. (This means "I don't know" and can be used as a way to decline a request.)

* Je ne peux pas. (This means "I can't" and is used to politely decline something you are unable to do.)

* Je préfère ne pas. (This means "I prefer not to" and is a more polite way to decline something.)

The best way to say no depends on the situation and your relationship with the person you are speaking to.
