A type of marine worm that lives in the sand and is often used as bait for fishing.
The fisherman used a clamworm to catch more fish.
Clamworm is formed from "clam" (from Old English *clam*, meaning a type of shellfish) and "worm" (from Old English *wyrm*, meaning serpent or worm). The word refers to a type of marine worm that resembles a clam in its habitat or appearance.
Think of a 'clam' as a shellfish and 'worm' as a creature that resembles a worm — together, they describe a marine worm that has clam-like features.
