'alienated' originates from Latin, specifically the word 'alienatus,' where 'alienare' meant 'to make another's, estrange.'

'alienatus' transformed into the Old French word 'aliener,' and eventually became the modern English word 'alienate' through Middle English.

Initially, it meant 'to make another's or estrange,' and over time it evolved into its current meaning of 'feeling isolated or estranged.'
