'expatriate' originates from Latin, specifically the word 'expatriare,' where 'ex-' meant 'out of' and 'patria' meant 'native country.'

'expatriare' transformed into the French word 'expatrier,' and eventually became the modern English word 'expatriate' through Middle English.

Initially, it meant 'to banish from one's native country,' but over time it evolved into its current meaning of 'to live outside one's native country.'
