'prosecute' originates from Latin, specifically the word 'prosequi,' where 'pro-' meant 'forward' and 'sequi' meant 'to follow.'

'prosequi' transformed into the Old French word 'prosecuter,' and eventually became the modern English word 'prosecute' through Middle English.

Initially, it meant 'to follow forward,' but over time it evolved into its current meaning of 'to initiate legal proceedings.'
