noun a thief who steals from someone by threatening violence
originInherited from Middle English robbour, robbere, either directly taken from or from a calque of Old French robeor. Equivalent to rob + -er. Compare reaver (“robber, plunderer”), a native English word derived from Proto-Germanic *raubārijaz that is ultimately of more or less the same composition as robber. And compare rover (“a pirate”), another word of the same composition.
