IPA: //ˈsnoʊfiːld//
KK: /snoʊfild/
A large area covered with snow, often found in cold regions or at the top of mountains.
The hikers set up camp on the snowfield, surrounded by towering peaks.
Snowfield → It is formed from "snow" (from Old English *snāw*, meaning frozen precipitation) and "field" (from Old English *feld*, meaning open land or area). The word "snowfield" refers to an area of land covered with snow.
Think of an 'open area' ('field') that is covered with 'frozen precipitation' ('snow') — that's what a snowfield is.
