Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid over-translating as just 'open' (открыть). The word specifies the *method* of opening. Better fit is 'отодвинуть защелку', 'расстегнуть защелку', or 'отпереть на защелке'.
Common Mistakes
- Using 'unlatch' for complex locks (e.g., deadbolts, digital locks). Confusing with 'unlock', which requires a key or code. Incorrect: 'I unlatched the door with my key.'
