Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'раззажимать' – it's non-existent. Use 'снимать зажим/струбцину', 'ослаблять зажим'.
- Do not confuse with 'unclench' (разжимать кулак). 'Unclamp' is for tools/devices.
Common Mistakes
- Using it intransitively (e.g., 'The vice unclamped' is odd; prefer 'The vice was unclamped' or 'The clamp came loose').
- Overusing in figurative contexts where 'deregulate', 'loosen', or 'free' are more natural.
