Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating directly as 'развязать' (untie/undo) or 'отделить' (separate physically). The core is breaking a functional link. 'Разъединить' or 'развязать (связь)' are closer.
- Confusion with 'discover' due to similar prefix 'de-'. 'Decouple' is not about finding.
Common Mistakes
- Using 'decouple' for simple physical separation of objects (e.g., 'He decoupled the books' is odd).
- Incorrect preposition: 'decouple with' (correct is 'decouple from').
- Spelling: 'decople' (missing 'u').
