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

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

Initially, it meant 'to burden or oppress,' but over time it evolved into its current meaning of 'a feeling of being wronged or treated unfairly.'
