Root Explanation

Unquenchable → It is formed from "un-" (meaning not) and "quench" (from Old English *cwencan*, meaning to extinguish or satisfy) and the suffix "-able" (meaning capable of). The word "unquenchable" describes something that cannot be extinguished or satisfied, often referring to an insatiable desire or thirst.

Memory Tip

Think of something that cannot be 'extinguished' ('quench') and is 'not' ('un-') capable of being satisfied — that's why unquenchable means an insatiable thirst or desire.
