Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'главная пружина' in figurative contexts, as it can sound overly literal. Use 'движущая сила', 'основная причина', or 'стержень' instead.
- Do not confuse with 'ключевой момент' (key moment); 'mainspring' refers to the cause, not the moment in time.
Common Mistakes
- Using it as a verb (e.g., 'It mainsprings the action' – incorrect).
- Misspelling as two words: 'main spring'.
- Overusing the figurative sense in informal contexts where 'main reason' or 'driving force' would be more natural.
