Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid calquing as "ночная сторона" in non-scientific contexts—it sounds unnatural. Use "тёмная сторона" for figurative meanings or specify "ночное полушарие" for planets.
Common Mistakes
- Using 'night side' as two words in technical writing (standard is one word). Confusing with 'dark side', which can have negative figurative connotations not always present in 'nightside'.
