Root Explanation

Airglow is formed from "air" (from Old English "aer", meaning the atmosphere or sky) and "glow" (from Old English "glowan", meaning to shine or emit light). The word describes the faint light emitted by the atmosphere, particularly visible at night.

Memory Tip

Think of the 'atmosphere' ('air') shining or 'emitting light' ('glow') — that's what airglow means.
