How do we say how are you in French?

"How are you?" in French can be said in a few ways, depending on the formality of the situation:

Formal:

* Comment allez-vous? (This is the most formal way to ask.)

Informal:

* Comment vas-tu? (This is used with friends, family, and people you know well.)

* Ça va? (This is the most casual way to ask, literally meaning "It goes?")

More casual and friendly:

* Quoi de neuf? (What's new?)

* Comment ça va? (How's it going?)

Remember:

* You can also add "bien" (good) or "mal" (bad) after the question to indicate you're doing well or not.

* If you're asking "how are you" in the context of someone's health, you might say "Comment vous sentez-vous?" (Formal) or "Comment tu te sens?" (Informal).

Hope this helps!
