How do you say may I help in French?

There are a few ways to say "May I help you?" in French, depending on the context and level of formality:

Formal:

* Puis-je vous aider? (Pwee-zhuh voo eh-deh?) - This is the most common and polite way to ask.

* Y a-t-il quelque chose que je puisse faire pour vous? (Ee ah-tee-eel kel-kuh-shoz kuh zhuh pweese fehr poor voo?) - This translates to "Is there anything I can do for you?"

Informal:

* Puis-je t'aider? (Pwee-zhuh teh-deh?) - This is the informal version of the first sentence, used with friends or family.

* Tu veux de l'aide? (Too vuh de lah-de?) - This translates to "Do you want help?"

Other options:

* Besoin d'aide? (Buh-zwan deh-de?) - This is a very casual way to ask "Need help?"

* Est-ce que vous cherchez quelque chose? (Eh-skuh voo sher-sheh kel-kuh-shoz?) - This translates to "Are you looking for something?"

The best option will depend on the specific situation and your relationship with the person you're talking to.
