Etymology

The word "rampant" originates from Old French rampant, the present participle of ramper ("to climb, rear up"), which likely derives from a Germanic root meaning "to bend or crawl." The heraldic sense (standing on hind legs) emerged in Middle English, reflecting the imagery of an animal rearing aggressively. Over time, it broadened metaphorically to describe unchecked growth or intensity, aligning with the idea of something "rising uncontrollably."
