'enlistee' originates from the English word 'enlist', which comes from the Old French word 'enlister', where 'en-' meant 'in' and 'lister' meant 'to list or enroll'.

'enlister' transformed into the English word 'enlist', and eventually became the modern English word 'enlistee'.

Initially, it meant 'to enroll or register', but over time it evolved into its current meaning of 'a person who has enlisted'.
