IPA: /ˈwʊdˌwɜːm/
KK: /ˈwʊdˌwɜrm/
A small insect larva that lives in wood and creates holes as it eats through it.
The old furniture was damaged by woodworm, leaving many tiny holes in the wood.
Woodworm is formed from "wood" (from Old English *wudu*, meaning the material derived from trees) and "worm" (from Old English *wyrm*, meaning a serpent or a small creature). The term refers to a small creature that infests and damages wood, resembling a worm.
Think of 'wood' as the material from trees and 'worm' as a small creature that can damage it — that's why woodworm refers to a creature that infests wood.
