Root Explanation
Ruthlessness → It is formed from "ruth" (from Old English *rūð*, meaning sorrow or compassion) and the suffix "-lessness" (meaning without). The word describes a state of being without compassion or pity.
Memory Tip
Think of 'ruth' meaning compassion and 'lessness' meaning without — so ruthlessness means being without compassion.
