Icefall → The word is formed from "ice" (from Old English "is", meaning frozen water) and "fall" (from Old English "feallan", meaning to fall). An icefall refers to a mass of ice that falls or cascades down a slope or cliff, resembling a waterfall.
Think of 'frozen water' ('ice') that 'falls' ('fall') down a slope, which helps you remember that an icefall is a cascade of ice.
