Root Explanation

Biodegradable is formed from "bio-" (from Greek "bios", meaning life) and "degradable" (from Latin "degradare", meaning to reduce in quality or value). The word refers to substances that can be broken down by living organisms, thus returning to the environment without causing harm.

Memory Tip

Think of 'life' ('bio-') breaking down materials that can be 'reduced' ('degradable') naturally, which is why biodegradable means capable of being broken down by living organisms.
