verglas
C2Formal, Literary, Technical (Meteorology/Climbing)
Definition
Meaning
A thin, transparent layer of ice, often found on rock surfaces or roads.
A specific type of hazardous, slippery ice coating, particularly one that forms from frozen rain or drizzle on cold surfaces, often invisible or hard to see.
Linguistics
Semantic Notes
Primarily a technical term from mountaineering and meteorology. It denotes a specific, often treacherous, type of ice formation, not just any ice on the ground (like black ice on roads, which is a broader, more common term).
Dialectal Variation
British vs American Usage
Differences
The word is known in both varieties but is extremely rare in everyday use. It is marginally more likely to be encountered in UK climbing/mountaineering literature due to the influence of French Alpine terminology.
Connotations
Technical precision, danger, alpine conditions.
Frequency
Very low frequency in both. Slightly higher in specialized technical texts (climbing guides, meteorological reports) than in general language.

Translation Traps (for Russian speakers)
- Do not confuse with general 'лёд' (ice) or 'гололёд' (which is more general ice on ground/roads). Verglas is a specific, thin, often transparent subtype.
Common Mistakes
- Using it to refer to any ice on a road (use 'black ice').
- Mispronouncing it with a hard 'g' (it's /ɡlɑː/, like 'glacier').
- Using it in everyday weather reports.
