'repurchase' originates from Latin, specifically the word 're-' meaning 'again' and 'purchasare' meaning 'to buy'.

'purchasare' transformed into the Old French word 'pourchacier', and eventually became the modern English word 'purchase', with 're-' added to indicate repetition.

Initially, it meant 'to buy again', and this meaning has largely remained the same in modern usage.
