Root Explanation

Thermograph → It is formed from "thermo-" (from Greek "thermos", meaning heat) and "graph" (from Greek "grapho", meaning to write or record). The word "thermograph" refers to a device that records temperature changes, essentially writing down heat measurements.

Memory Tip

Think of 'heat' ('thermo-') being 'written down' ('graph') — that's how a thermograph records temperature.
