emigration
UK: ˌemɪˈɡreɪʃən | US: ˌemɪˈɡreɪʃən
n. the act of leaving one's own country to settle permanently in another
n. the group of people who emigrate
The word "emigration" originates from Latin emigrare (e- "out" + migrare "to move"). The prefix e- (variant of ex-) signifies "out," while migrare means "to move or migrate." Combined, they form emigrare, meaning "to move out (of a place)." The suffix -ation was added in Late Latin to form a noun indicating the action or process. Over time, "emigration" specifically came to denote leaving one's native country to settle elsewhere, distinguishing it from general migration.
