'injure' originates from Latin, specifically the word 'injuriare,' where 'in-' meant 'not' and 'jurare' meant 'to swear or take an oath.'

'injuriare' transformed into the Old French word 'injurier,' and eventually became the modern English word 'injure' through Middle English.

Initially, it meant 'to do wrong or injustice,' but over time it evolved into its current meaning of 'to cause harm or damage.'
