Root Explanation

Exothermic → It is formed from "exo-" (meaning outside) and "thermē" (meaning heat). The word describes a process that releases heat to the outside environment.

Memory Tip

Think of a process that releases heat 'outside' ('exo-') — that's why exothermic means producing heat outward.
