IPA: //ˈsʌnˌbɛd//
KK: /sʌnˌbɛd/
A piece of furniture that uses special lights to give a person a tan, similar to lying in the sun.
She decided to use the sunbed to get a tan before her vacation.
Sunbed → The word is formed from "sun" (from Old English *sunne*, meaning the star that provides light and warmth) and "bed" (from Old English *bedd*, meaning a place to lie down). A sunbed is a place designed for lying down under artificial sunlight.
Think of the 'sun' providing light and warmth while you lie down on a 'bed' — that's what a sunbed is for.
