'depart' originates from Old French, specifically the word 'departir', where 'de-' meant 'away' and 'partir' meant 'to divide or separate'.

'departir' transformed into the Middle English word 'departen', and eventually became the modern English word 'depart'.

Initially, it meant 'to divide or separate', but over time it evolved into its current meaning of 'to leave or go away'.
