'unemploy' originates from the prefix 'un-' meaning 'not' and the word 'employ' from Old French 'emploier', which meant 'to use or apply'.

'employ' changed from the Old French word 'emploier' and eventually became the modern English word 'employ'.

Initially, 'employ' meant 'to use or apply', but over time it evolved into its current meaning of 'to hire or provide work for'.
