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.
