'enrollment' originates from the Old French word 'enroller', where 'en-' meant 'in' and 'roller' meant 'to roll'.

'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 roll or list', but over time it evolved into its current meaning of 'the act of enrolling'.
