'reassign' originates from the prefix 're-' meaning 'again' and the word 'assign' from Latin 'assignare', where 'ad-' meant 'to' and 'signare' meant 'mark'.

'assignare' transformed into the Old French word 'assigner', and eventually became the modern English word 'assign'.

Initially, it meant 'to mark or designate', but over time it evolved into its current meaning of 'to allocate or designate a task or position'.
