Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation from Russian 'выключать' when referring to abstract concepts; use 'lose interest' or 'disengage' instead. 'Switch-off' as a noun doesn't directly correlate to a single Russian word.
Common Mistakes
- Using 'close off' or 'shut off' for electronic devices (less common). Incorrect: 'Switch off the water' (use 'turn off').
