'unspoiled' originates from the prefix 'un-' meaning 'not' and the word 'spoiled', which comes from the Old French 'espoillier', meaning 'to strip or plunder'.

'espoillier' transformed into the Middle English word 'spoylen', and eventually became the modern English word 'spoil'. The prefix 'un-' was added to form 'unspoiled'.

Initially, 'spoil' meant 'to strip or plunder', but over time it evolved to mean 'to damage or ruin'. 'Unspoiled' retains the meaning of 'not damaged'.
