Root Explanation

Photosensitive → It is formed from "photo-" (from Greek "phōs", meaning light) and "sensitive" (from Latin "sensitivus", meaning capable of feeling or perceiving). The word describes something that is capable of responding to or affected by light.

Memory Tip

Think of 'light' ('photo-') and something that can 'feel' or respond ('sensitive') — that's why photosensitive means responsive to light.
