IPA: /ˈkwɛnʧləs/
KK: /ˈkwɛnʧləs/
Describing something that cannot be satisfied or extinguished, often used to refer to desires or needs that are endless.
Her quenchless thirst for knowledge drove her to read every book she could find.
Quenchless is formed from "quench" (from Old English *cwencan*, meaning to extinguish or put out) and "-less" (meaning without). The word describes a state of being without the ability to be quenched or satisfied.
Think of 'quench' as putting out a fire or satisfying thirst, and '-less' means without. So, quenchless means being without satisfaction or the ability to be satisfied.
