Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'двенадцатиперстная кишка' which is the exact, direct equivalent. Ensure the translation is precise and not shortened to just 'кишка' (intestine), which is too vague.
Common Mistakes
- Mispronunciation (e.g., /duːˈɒdɪnəm/).
- Misspelling (e.g., 'duedonum', 'duodenem').
- Using it as a general term for 'stomach' or 'intestine'.
