'purchase' originates from Old French, specifically the word 'pourchacier,' where 'pour-' meant 'for' and 'chacier' meant 'to chase.'

'pourchacier' transformed into the Middle English word 'purchasen,' and eventually became the modern English word 'purchase.'

Initially, it meant 'to chase or pursue something,' but over time it evolved into its current meaning of 'to buy or acquire something.'
