reaver

Etymology

Came into English from Middle English revere (also spelled revour, reiver, refar, reavere), from Old English rēafere (“reaver; robber; spoiler”), which can be seen as reave plus -er. It is cognate with Saterland Frisian Roower, Dutch rover, German Räuber, Swedish rövare, and Icelandic raufari. Compare robber and rover.
