Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'грубо выгнать' (to rudely kick out). The phrasal verb is about creation, not expulsion. The correct conceptual equivalent is 'набросать', 'сделать черновик', 'создать эскиз'.
Common Mistakes
- Using 'rough up' (to beat someone) instead of 'rough out'. Confusing it with the adjective 'rough' meaning 'approximate' (e.g., 'a rough estimate').
