Common Pitfalls

Translation Traps (for Russian speakers)

  • Avoid direct translation for 'first-class degree' – it's not 'первоклассная степень', but 'диплом с отличием' or 'степень первого класса'.
  • In travel, 'первый класс' is correct, but be aware it's a fixed category, not a general adjective here.

Common Mistakes

  • Using it as an adverb without a hyphen: 'He travelled first class' (correct) vs. 'He travelled first-classly' (incorrect).
  • Confusing 'first class' (category) with 'first-rate' (general adjective).
