Etymology

Borrowed from Middle French rempart (“rampart of a fort”), from Old French remparer (“to defend, fortify, inclose with a rampart”), from re- (“again”) + emparer (“defend, fortify, surround, seize, take possession of”), from Old Occitan amparer, from Vulgar Latin *anteparō (“to prepare”), from ante- + parō (“to prepare”).
