'reprieve' originates from Middle English, specifically the word 'repreven,' where 're-' meant 'again' and 'preven' meant 'to prove or test.'

'repreven' transformed into the modern English word 'reprieve' through the influence of Old French 'reprover.'

Initially, it meant 'to test again,' but over time it evolved into its current meaning of 'to delay punishment or provide relief.'
