Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid calquing Russian 'открыть ключом' (open with a key); 'unlock' already contains the 'with a key' meaning.
- Do not confuse with 'discover' or 'reveal' ('раскрыть') in all contexts; 'unlock' implies a prior barrier.
- The verb 'разблокировать' is a direct equivalent for devices/tech.
Common Mistakes
- Incorrect: 'She unlocked the door with a key.' (Redundant, but not grammatically wrong.) Better: 'She unlocked the door.'
- Incorrect: 'The book unlocked me new ideas.' Correct: 'The book unlocked new ideas for me.'
- Incorrect: 'Can you unlock the light?' Correct: 'Can you turn on/switch on the light?'
