'rampart' originates from Old French, specifically the word 'remparer,' where 're-' meant 'again' and 'parer' meant 'to prepare or defend.'

'remparer' transformed into the Middle English word 'rampart,' and eventually became the modern English word 'rampart.'

Initially, it meant 'to fortify or defend,' but over time it evolved into its current meaning of 'a defensive wall or barrier.'
