ruthless
UK: ˈruːθləs | US: ˈruːθləs
adj. showing no pity or compassion; merciless
adj. harsh or cruel in manner or action
The word "ruthless" combines "ruth," an archaic noun meaning "compassion" or "pity" (derived from the Middle English "reuthe," itself from Old Norse "hryggð"), with the suffix "-less," meaning "without." The term emerged in the late 14th century, originally describing someone devoid of remorse or kindness. Over time, "ruth" fell out of common usage, but "ruthless" endured, solidifying its modern meaning of extreme cruelty or indifference.
