Photodegradable → It is formed from "photo-" (from Greek "phōs", meaning light) and "degradable" (from Latin "degradare", meaning to reduce in quality or to break down). The word "photodegradable" refers to materials that can break down or degrade when exposed to light, particularly sunlight.
Imagine materials that can 'break down' ('degradable') when they are exposed to 'light' ('photo-'). This helps you remember that photodegradable means capable of breaking down in the presence of light.
