🎤Pronunciation
🌳Etymology
Origin
This word originates from Old English 'cwencan' (to extinguish, quench), combined with the Germanic negative prefix 'un-' and the productive suffix '-able' (capable of). The base verb 'quench' historically referred to extinguishing fire or satisfying thirst, and the prefix-suffix combination negates this capacity, creating a word meaning 'incapable of being extinguished or satisfied'.
Breakdown
un- (not, negation) + quench (from Old English cwencan, meaning to extinguish or satisfy) + -able (capable of, able to be). The construction literally means 'not able to be quenched or extinguished'.
