Root Explanation

Pyrolyze → It is formed from "pyro-" (from Greek "pur", meaning fire) and "lyze" (from Greek "lyzein", meaning to break down or loosen). The word "pyrolyze" means to break down or decompose organic material using heat, typically in the absence of oxygen.

Memory Tip

Think of 'fire' ('pyro-') breaking down materials ('lyze') — that's how pyrolyze means to decompose using heat.
