'enroll' originates from Old French, specifically the word 'enroller,' where 'en-' meant 'in' and 'rolle' meant 'roll or list.'

'enroller' transformed into the Middle English word 'enrollen,' and eventually became the modern English word 'enroll.'

Initially, it meant 'to enter a name on a list,' but over time it evolved into its current meaning of 'to register or sign up.'
