Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating it as 'international silence of the radio' (*международная тишина радио). The phrase is a fixed unit. A direct equivalent is 'международное радиомолчание'.
- Do not confuse with simple 'radio silence' (*радиотишина), which can be local. 'International' implies a coordinated multi-party action.
Common Mistakes
- Using it to describe a simple technical fault ('There's an international radio silence because the mast is down').
- Using 'worldwide' instead of 'international' ('worldwide radio silence') – the standard fixed phrase is 'international'.
- Incorrect preposition: 'silence *from the radio' instead of 'radio silence'.
