The word "raider" originates from the verb "raid," which entered English in the early 15th century from Scots or northern Middle English, meaning "a military expedition on horseback." "Raid" itself traces back to Old English rād (a riding, journey) and Proto-Germanic raidō (a ride, raid). The suffix "-er" (from Old English -ere) denotes an agent performing the action, turning "raid" into "raider"—literally "one who raids." Historically, raiders were often mounted attackers, reflecting the word’s equestrian roots. Over time, it expanded to include pirates, corporate aggressors, and sports teams (e.g., "Oakland Raiders").
The Vikings were feared raiders along the European coastlines.
Corporate raiders often target undervalued companies for takeover.
The police arrested the bank raider after a high-speed chase.
During the war, enemy raiders destroyed supply lines under cover of darkness.
The football team earned the nickname "Raiders" for their aggressive playing style.
