C1/C2; Low-frequency, specialized term.Technical (geology, glaciology, mountaineering), literary, journalistic.
Definition
Meaning
A steep, flowing section of a glacier, often resembling a frozen waterfall, where the ice moves over a sudden drop in the underlying bedrock, causing intense crevassing and chaotic ice formations.
Metaphorically, can refer to any large, sudden, or dangerous accumulation or collapse of ice. In fantasy and gaming contexts, sometimes used to describe a magical or environmental effect involving falling ice.
Linguistics
Semantic Notes
Primarily a concrete noun for a glaciological feature. Its metaphorical use is rare but evocative. Not to be confused with 'icicle' (a hanging spike of ice) or 'avalanche' (a mass of snow/ice falling down a mountain).

Common Pitfalls
Translation Traps (for Russian speakers)
- Не переводить как 'ледопад' (это калька, не устоявшийся термин). Стандартный термин - 'ледопадный участок' или 'ледопад' в узкоспециальной литературе, но чаще используется описание.
- Не путать с 'обвалом льда' (ice collapse/avalanche).
Common Mistakes
- Using 'icefall' to mean a fall on ice (that's 'a slip on the ice').
- Spelling as two words: 'ice fall'.
- Confusing it with 'waterfall'.
