'uninjured' originates from the prefix 'un-' meaning 'not' and the word 'injured' from Latin 'injuria' meaning 'wrong' or 'harm'.

'injuria' transformed into the Old French word 'injurie', and eventually became the modern English word 'injure', with 'uninjured' forming as a negation.

Initially, it meant 'not harmed or wronged', and this meaning has largely remained the same in modern usage.
