Formal:
* "Comment vous appelez-vous ?" (pronounced "koh-moh voo za-pleh-vay voo?") This is the most formal way to ask someone's name, and you would use it for someone you don't know well or someone older than you.
Informal:
* "Comment t'appelles-tu ?" (pronounced "koh-moh tap-pel too?") This is a more informal way to ask someone's name, and you would use it with friends, family, or people you know well.
Even More Informal:
* "C'est quoi ton nom ?" (pronounced "say kwa ton nohm?") This is a very informal way to ask someone's name, and you would only use it with very close friends.
Adding Politeness
* "Excusez-moi, comment vous appelez-vous ?" (pronounced "eks-kyoo-zay mwa, koh-moh voo za-pleh-vay voo?") This is a polite way to ask someone's name, even if you are using the formal form.
Remember:
* French is a gendered language, so the verb "appeler" changes depending on whether you are addressing a man or a woman.
* The "tu" form is used for informal situations, while the "vous" form is used for formal situations.
