How do you say Are back yet in French?

There isn't a direct translation of "Are you back yet?" in French that captures the exact meaning and informal tone. Here are some options, depending on the context:

Formal:

* Êtes-vous déjà de retour ? (Are you already back?)

* Êtes-vous rentré(e) ? (Have you returned?)

Informal:

* Tu es déjà de retour ? (Are you back already?)

* T'es déjà rentré(e) ? (Are you back already? - even more informal)

* Vous êtes rentrés ? (Are you back? - informal, but polite)

* T'es rentré(e) ? (Are you back?) - this is very informal and sounds more like a friend asking

More conversational:

* Vous êtes revenu(e) ? (Have you come back?)

* Tu es revenu(e) ? (Have you come back? - informal)

The best option depends on the context of your conversation and your relationship with the person you're speaking to.
