'unemployable' originates from the prefix 'un-' meaning 'not' and the word 'employable', which comes from 'employ', derived from the Latin 'implicare', meaning 'to engage or involve'.

'employable' changed from the Old French word 'employer', which meant 'to use or apply', and eventually became the modern English word 'employ'.

Initially, it meant 'not able to be used or applied', but over time it evolved into its current meaning of 'not suitable for employment'.
