Did you know there are actual glowworms that light up in the dark?

Really? I thought they were just a myth or something!

I would love to see them in person; that sounds magical!

Root Explanation

Glowworm → The word is formed from "glow" (from Old English *glowan*, meaning to shine or emit light) and "worm" (from Old English *wyrm*, meaning serpent or creature). A glowworm is a creature that shines or emits light, resembling a worm.

Memory Tip

Think of a creature that 'shines' ('glow') like a 'worm' — that's why a glowworm is a light-emitting creature.
