Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation or splitting into 'immuno' and 'suppressive'. The standard Russian equivalent is 'иммунодепрессивный' or 'иммуносупрессивный'.
- Do not confuse with 'immunostimulating' ('иммуностимулирующий'), which has the opposite meaning.
Common Mistakes
- Misspelling: 'immunosupressive' (missing one 'p').
- Incorrect noun form: Using 'immunosuppressive' as a countable noun without 'drug' or 'agent' (e.g., 'He is on an immunosuppressive' is informal; 'He is on an immunosuppressive drug' is standard).
