Definition

Meaning

A long, wavelike ridge of hard snow formed by the wind, common in polar and high-altitude regions.

A sharp, irregular ridge or groove formed on a snow surface by wind erosion and deposition. The plural form 'sastrugi' is often used to describe a field of such formations.

Linguistics

Semantic Notes

Primarily a term of polar and alpine geography. It denotes a specific, sharp, wind-sculpted formation, distinct from general snow dunes or drifts.

Dialectal Variation

British vs American Usage

Differences

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Direct borrowing from Russian 'заструга' (zastruga). Meaning is identical, so no trap. However, the English plural is typically 'sastrugi', following the Latin/Greek convention, rather than a Russian plural form.

Common Mistakes

  • Mispronouncing as /sæsˈtruːdʒə/ or /ˈsæstrʊɡə/.
  • Using 'sastruga' as a plural (the plural is 'sastrugi').
  • Confusing it with a general snowdrift or cornice.

FAQ

Frequently Asked Questions

The standard plural is 'sastrugi'.

In polar regions (Antarctica, Arctic) and on high-altitude glaciers and snowfields where strong, persistent winds occur.

Yes, it is a loanword from Russian (заструга) fully adopted into English, primarily in technical and exploratory contexts.

Yes, though rare. To 'sastruga' means to form into sastrugi, and 'sastrugied' is used as a past participle/adjective (e.g., 'a sastrugied plain').
