'persecute' originates from Latin, specifically the word 'persequi,' where 'per-' meant 'through' and 'sequi' meant 'to follow.'

'persequi' transformed into the Old French word 'persecuter,' and eventually became the modern English word 'persecute' through Middle English.

Initially, it meant 'to follow with harmful intent,' but over time it evolved into its current meaning of 'to subject to hostility and ill-treatment.'
