KK: /ˈflaɪˌpeɪpər/
A type of paper that is covered with a sticky substance to trap flies and other insects.
We hung the flypaper in the kitchen to catch any pesky flies.
Flypaper is a compound word formed from "fly" (from Old English *flēoge*, meaning a small flying insect) and "paper" (from Latin *papyrus*, meaning a writing material made from the pith of the papyrus plant). The word describes a type of paper designed to catch flies, combining the idea of the insect with the material used to trap it.
Think of a small flying insect ('fly') getting stuck to a sticky material ('paper') — that's what flypaper is designed to do.
