'devisor' originates from Old French, specifically the word 'deviser,' where 'de-' meant 'apart' and 'viser' meant 'to see or to plan.'

'deviser' transformed into the Middle English word 'devisour,' and eventually became the modern English word 'devisor.'

Initially, it meant 'one who plans or sees apart,' but over time it evolved into its current meaning of 'a person who creates or invents something.'
