IPA: /ˈwɔːtəfɔːl/
KK: /ˈwɔːtərˌfɔːl/
A natural feature where water flows over a vertical drop or cliff, creating a beautiful cascade.
The waterfall was a stunning sight, with water crashing down into the pool below.
Waterfall is formed from "water" (from Old English *wæter*, meaning liquid that falls from the sky or flows in rivers) and "fall" (from Old English *feallan*, meaning to fall or drop). The word describes a place where water falls from a height, typically over a cliff or rock.
Imagine water flowing down and 'falling' from a height — that's how you can remember that a waterfall is where water drops down.
