IPA: /ˈθɜːrməˌɡræm/
KK: /ˈθɜrməˌɡræm/
A type of record that shows temperature changes, created by a device called a thermograph.
The doctor examined the thermogram to check for any unusual heat patterns in the patient's body.
Thermogram → It is formed from "thermo-" (from Greek "thermos", meaning heat) and "-gram" (from Greek "gramma", meaning something written or recorded). The word "thermogram" refers to a written or recorded representation of heat.
Think of 'heat' ('thermo-') being 'recorded' ('-gram') — that's what a thermogram does.
