IPA: //ˈhaʊsˌwɔːrmɪŋ//
KK: /ˈhaʊsˌwɜrmɪŋ/
A party or celebration that is held to welcome someone into a new home.
We are having a housewarming this weekend to celebrate our new apartment.
Housewarming is formed from "house" (from Old English "hus", meaning a dwelling or shelter) and "warming" (from the verb "warm", meaning to make warm). The word refers to a gathering held to celebrate the warmth and comfort of a new home.
Think of a 'house' as a 'dwelling' and 'warming' as making it cozy — that's why housewarming is a celebration of making a new home warm and inviting.
