Root Explanation

Thermostable is formed from "thermo-" (from Greek "thermos", meaning heat) and "stable" (from Latin "stabilis", meaning standing firm or fixed). The word describes something that remains stable or unchanged when exposed to heat.

Memory Tip

Think of 'heat' ('thermo-') and something that 'stands firm' ('stable') — that's why thermostable means something that stays unchanged when heated.
