Root Explanation

Photoionized → It is formed from "photo-" (from Greek "phōs", meaning light) and "ionized" (from "ion", meaning to go). The word describes the process of ions being created by the action of light.

Memory Tip

Think of 'light' ('photo-') causing particles to 'go' or become charged ('ionized'). This helps you remember that 'photoionized' refers to ions created by light.
