'fulfill' originates from Old English, specifically the word 'fullfyllan,' where 'full' meant 'full' and 'fyllan' meant 'to fill.'

'fullfyllan' transformed into the Middle English word 'fulfille,' and eventually became the modern English word 'fulfill.'

Initially, it meant 'to fill fully,' but over time it evolved into its current meaning of 'to complete or achieve something as required or expected.'
