Root Explanation
Thermostat → It is formed from "thermo-" (from Greek "thermos", meaning heat) and "statos" (from Greek, meaning standing or stationary). The word "thermostat" refers to a device that stands or maintains a certain heat level.
Memory Tip
Think of 'heat' ('thermo-') being 'maintained' ('statos') — that's what a thermostat does.
