'unexploited' originates from the prefix 'un-' meaning 'not' and the word 'exploit', which comes from Latin 'exploitatio', meaning 'to utilize or make use of'.

'exploit' changed from the Old French word 'exploiter' and eventually became the modern English word 'exploit'.

Initially, 'exploit' meant 'to accomplish or achieve', but over time it evolved into its current meaning of 'to utilize or make use of'.
