IPA: /ˈsprɪŋˌhaʊs/
KK: /sprɪŋhaʊs/
A small building built over a natural water source, used to keep food cool and fresh.
The farmer stored the milk in the springhouse to keep it cold.
Springhouse → The word is formed from "spring" (from Old English *springan*, meaning to leap or burst forth) and "house" (from Old English *hus*, meaning dwelling or shelter). A springhouse is a structure built over a spring, where water bursts forth, providing a source of fresh water.
Think of water 'bursting forth' ('spring') from a 'shelter' ('house') — that's why a springhouse is a shelter for a natural water source.
