icecap
C1Formal, Scientific, Geographical
Definition
Meaning
A permanent covering of ice over a large area, especially on the polar regions of a planet.
A mass of glacial ice, smaller than an ice sheet, covering a highland area like a mountain plateau; metaphorically, something that covers or seals a surface.
Linguistics
Semantic Notes
Primarily a geographical/glaciological term. The core concept is a permanent, extensive cover of ice, distinct from smaller glaciers or seasonal snow. In metaphorical use, it implies a smooth, unbroken, sealing layer.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or spelling. Both varieties use the solid compound 'icecap' or the hyphenated 'ice-cap'.
Connotations
Identical. Evokes climate science, polar exploration, and environmental concern.
Frequency
Slightly higher frequency in American media due to greater discussion of Arctic (Alaskan/Canadian) regions, but the term is equally standard in both varieties.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'ледник' (glacier) – an icecap is a specific, covering type of glacier. 'Ледяная шапка' is a direct and accurate translation.
- Avoid using 'айсберг' (iceberg), which is a floating piece of ice.
Common Mistakes
- Using 'icecap' to refer to any glacier. / Confusing 'icecap' with 'ice sheet' (ice sheets are continent-scale). / Spelling as two separate words: 'ice cap' is less common but acceptable; the solid form 'icecap' is standard in many dictionaries.

Frequently Asked Questions
An ice sheet is vastly larger, covering over 50,000 square kilometres (e.g., Antarctica, Greenland). An icecap is smaller, typically covering a mountain area or plateau less than 50,000 sq km.
Both 'icecap' (solid) and 'ice cap' (open) are found, but modern dictionaries often list 'icecap' as the primary headword, with 'ice cap' as a variant.
Yes, though it's not common. It can describe something that forms a smooth, sealing layer over a surface, e.g., 'An icecap of frost covered the windscreen.'
Yes, the term is used in planetary science. For example, Mars has permanent icecaps at its north and south poles, composed of water and carbon dioxide ice.
