Etymology
The word 'icefall' is a transparent compound formed within Modern English from two native Germanic elements. The first element, 'ice', descends from the Old English 'īs', a common Germanic term for frozen water. The second element, 'fall', originates from the Old English verb 'feallan', meaning to drop or descend. When combined, the term creates a vivid, descriptive image of a cascade or steep descent composed of ice. This logical compounding reflects a pattern in English where natural phenomena are named for their visual resemblance to more common objects or actions, in this case, likening a chaotic, crevassed section of a glacier to a waterfall that has been frozen in place.
