Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation of 'функциональный' for 'capable' or 'skilled'. In English, 'functional' relates to purpose/operation, not ability. E.g., 'He is a functional manager' means he manages a function (like finance), not that he is 'skilled at managing'.
Common Mistakes
- Using 'functional' to mean 'working well' in a general sense for people (e.g., 'He's very functional' sounds odd). Overusing to mean 'good'. Confusing with 'functioning' (e.g., 'The functional computer' vs. 'The computer is functioning').
