'engineer' originates from Old French, specifically the word 'engigneor,' where 'engigne' meant 'skill or cleverness.'

'engigneor' transformed into the Middle English word 'engineer,' and eventually became the modern English word 'engineer.'

Initially, it meant 'a constructor of military engines,' but over time it evolved into its current meaning of 'a person who designs, builds, or maintains engines, machines, or structures.'
