Root Explanation

Pyrolysis is formed from "pyro-" (from Greek "pur", meaning fire) and "lysis" (from Greek "lysis", meaning to break down or loosen). The word describes the process of breaking down organic material using heat in the absence of oxygen, effectively breaking it down with fire.

Memory Tip

Think of 'fire' ('pyro-') breaking things down ('lysis') — that's what pyrolysis means.
