IPA: /ˈkoʊtˌræk/
KK: /ˈkoʊtˌræk/
A piece of furniture with hooks or pegs where you can hang coats and other clothing items.
Please hang your coat on the coatrack when you come inside.
Coatrack is formed from "coat" (from Old English *cote*, meaning a covering or garment) and "rack" (from Old Norse *rǫkkr*, meaning a framework or support). The word refers to a framework or support specifically designed to hold coats.
Think of a 'covering' ('coat') being placed on a 'support' ('rack') — that's what a coatrack is for.
