The act of sending someone back to their home country or place of citizenship.
The repatriation of the refugees was a complex process that took several months.
Repatriation → It is formed from "re-" (meaning again) and "patria" (from Latin, meaning homeland or fatherland) and the suffix "-tion" (indicating the action or process). The word refers to the process of returning someone to their homeland or country of origin.
Think of 'returning' ('re-') to your 'homeland' ('patria') — that's what repatriation means.
