Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Not 'отрыв' in a casual sense (like отрыв от работы). It implies a traumatic, often complete, physical severing.
  • Beware of false friend 'авульсия' – a direct transliteration used only in very specific medical/legal contexts. 'Отрывной перелом' is an avulsion fracture.

Common Mistakes

  • Using it as a verb (to avulse exists but is hyper-technical).
  • Confusing with 'abrasion' (scraping) or 'evulsion' (archaic variant).
  • Using it to describe a slow, natural process like erosion.
