Common Pitfalls

Translation Traps (for Russian speakers)

  • Avoid direct calque or reordering like 'японский устрица'. Use established species name 'тихоокеанская устрица' or 'устрица гигас'.
  • The adjective 'Japanese' remains part of the fixed English name and should not be omitted in translation if the specific species is meant.

Common Mistakes

  • Using lowercase 'japanese' (should be capitalized as it's a proper adjective).
  • Omitting 'Japanese' and using just 'oyster', which loses the specific taxonomic/culinary reference.
  • Incorrect plural: 'Japanese oyster' (plural: Japanese oysters).
