IPA: /ˈfaɪərˌhaʊs/
KK: /ˈfaɪərˌhaʊs/
A building where firefighters and their equipment are located, and from which they respond to fires and emergencies.
The firehouse is always ready to respond to emergencies in the community.
Firehouse is formed from "fire" (from Old English "fyr", meaning flame or fire) and "house" (from Old English "hus", meaning dwelling or shelter). The word refers to a building or shelter specifically designed for housing fire-fighting equipment and personnel.
Think of a 'shelter' ('house') for 'flames' ('fire') — that's what a firehouse is, a place where fire-fighting resources are kept.
