IPA: /ˈbɔːrdɪŋhaʊs/
KK: /ˈbɔrdɪŋˌhaʊs/
A type of house where people can rent a room and also receive meals.
During college, I lived in a boardinghouse that provided breakfast and dinner.
Boardinghouse → It is formed from "boarding" (from the verb "board" meaning to provide meals and lodging, derived from Old English "bord" meaning table or food) and "house" (from Old English "hus" meaning dwelling or shelter). A boardinghouse is a place that provides meals and lodging, typically for travelers or workers.
Think of a 'table' ('bord') where meals are served and a 'shelter' ('hus') where people stay — that's what a boardinghouse offers.
