IPA: /ˈfiːldstoʊn/
KK: /ˈfildˌstoʊn/
A type of stone that is found naturally in fields and is often used for building purposes.
The old house was made of fieldstone, giving it a rustic appearance.
Fieldstone is formed from "field" (from Old English "feld", meaning open land or pasture) and "stone" (from Old English "stan", meaning rock or stone). The word refers to stones that are found in fields or open land, typically used in construction.
Think of 'open land' ('field') where you might find 'rocks' ('stone') — that's why fieldstone refers to stones found in fields.
