Etymology

The word "merciless" combines "mercy" (from Old French merci, meaning "pity" or "forgiveness," derived from Latin merces "reward, kindness") with the suffix "-less" (Old English -lēas, meaning "without"). The fusion creates a vivid contrast—literally "without mercy"—emphasizing harshness or indifference. Over time, it evolved to describe actions or behaviors devoid of compassion.
