Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation as "ранняя система предупреждения" which sounds unnatural. Use "система раннего предупреждения" or "система заблаговременного оповещения".
- Don't confuse with "сигнализация" (alarm) which implies immediate, not early, warning.
- In military contexts, "система ПРО" (missile defense) is related but not identical.
Common Mistakes
- Writing as three separate words without hyphens (*early warning system).
- Using as a verb (*'We need to early-warning-system this risk').
- Confusing with 'early detection system' (which identifies existing problems, not future ones).
