Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid a direct calque like '*иммуноподавлять*'. Use standard medical terminology: 'подавлять иммунитет' или 'проводить иммуносупрессивную терапию'. The verb form is less common in Russian than the noun/adjective.
Common Mistakes
- Using it intransitively (INCORRECT: 'The patient immunosuppressed.'). Confusing it with 'immunocompromised' (which is a state, not an action).
