IPA: /ˈsnoʊˌslaɪd/
KK: /ˈsnoʊˌslaɪd/
A large mass of snow that falls down a mountain, often causing danger or damage.
The snowslide buried several cars under tons of snow.
Snowslide is formed from "snow" (from Old English *snāw*, meaning frozen precipitation) and "slide" (from Old English *slīdan*, meaning to glide or move smoothly). The word describes the event of snow gliding or moving down a slope.
Imagine snow 'gliding' ('slide') down a mountain — that's what a snowslide is.
