Here are some examples:
* "Ils se sont retrouvés après dix ans." (They reunited after ten years.)
* "J'espère vous retrouver bientôt." (I hope to reunite with you soon.)
* "Le groupe a décidé de se retrouver pour un concert." (The band decided to reunite for a concert.)
Other possible translations include:
* "Réunir" (to bring together) - This is more about the act of bringing people or things together, rather than the act of reuniting.
* "Se rassembler" (to gather) - This is a more general term for coming together, but it can also be used to mean reunite.
* "Rapprocher" (to bring closer) - This implies a more emotional reunion, where people are brought closer together after a period of separation.
The best translation will depend on the specific context.
