Returnee → It is formed from "re-" (meaning again) and "turn" (from Old French *torner*, meaning to turn). The word "returnee" refers to someone who turns back or comes back again, typically after being away.
Think of someone coming back 'again' ('re-') and 'turning' back to where they were — that's why a returnee is someone who has come back.
