How do you say i only speak French in French?

There are a few ways to say "I only speak French" in French, depending on the level of formality and nuance you want to convey:

Formal:

* Je ne parle que le français. (This is the most literal translation and sounds very formal.)

* Je parle uniquement français. (This is also very formal and emphasizes "only".)

Informal:

* Je parle juste français. (This means "I only speak French" and sounds more casual.)

* Je suis francophone. (This means "I am a French speaker" and is a more common way to say it.)

Adding context:

* Je ne parle pas anglais, juste français. (This means "I don't speak English, just French" and adds specific context.)

* Je comprends un peu d'anglais, mais je ne parle que français. (This means "I understand a little English, but I only speak French" and clarifies your language skills.)

The best way to say it depends on the specific context and the person you are talking to.
