Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate literally as 'сжечь прочь'. For calories/energy, use 'сжигать' (калории). For fog, use 'рассеиваться' (о тумане). 'Burn off steam' idiom is 'выпускать пар'.
Common Mistakes
- Using 'burn out' instead of 'burn off' ('burn out' means to exhaust completely, often non-physically). Confusing with 'burn up' (which implies complete destruction or having a fever). Incorrect particle order: 'burn it off' is correct, not 'burn off it'.
