'appropriately' originates from Latin, specifically the word 'appropriatus,' where 'ad-' meant 'to' and 'proprius' meant 'own.' 'Returned' originates from Old French, specifically the word 'retourner,' where 're-' meant 'back' and 'tourner' meant 'to turn.'

'appropriatus' transformed into the Middle English word 'appropriat,' and eventually became the modern English word 'appropriate.' 'Retourner' transformed into the Middle English word 'returnen,' and eventually became the modern English word 'return.'

Initially, 'appropriate' meant 'to make one's own,' but over time it evolved into its current meaning of 'suitable or proper.' 'Return' initially meant 'to turn back,' and this meaning has largely remained the same in modern usage.
