Unable to leave a place because of a lot of snow blocking the way.
The family was snowbound in their cabin for three days due to the blizzard.
Snowbound → It is formed from "snow" (from Old English *snāw*, meaning frozen precipitation) and "bound" (from Old English *bund*, meaning tied or confined). The word "snowbound" describes being confined or trapped by snow.
Imagine being 'tied' ('bound') by 'frozen precipitation' ('snow') — that's why snowbound means being trapped by snow.
