'aggrieved' originates from Old French, specifically the word 'aggriever,' where 'a-' meant 'to' and 'grever' meant 'to burden or harm.'

'aggriever' transformed into the Middle English word 'agreve,' and eventually became the modern English word 'aggrieve.'

Initially, it meant 'to burden or harm,' but over time it evolved into its current meaning of 'feeling resentment at unfair treatment.'
