Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation 'терминальная болезнь' in casual speech; it sounds highly technical. 'Смертельное заболевание' is more common, but 'неизлечимая болезнь' (incurable illness) is often used as a softer synonym.
Common Mistakes
- Using 'terminal' to mean 'very serious' but potentially curable (e.g., 'a terminal flu').
- Confusing 'terminal' with 'chronic' (long-lasting but not necessarily fatal).
- Misspelling as 'termal illness'.
