Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation as 'на ролле' or 'на катушке'. The correct conceptual equivalent is 'на волне успеха', 'в ударе', 'в удачной полосе'.
- Do not confuse with 'roll' as in bread roll ('булочка') or to roll a dice ('катить').
Common Mistakes
- Using it without the preposition 'on' (e.g., 'He is a roll' is incorrect).
- Using the article 'the' instead of 'a' (e.g., 'on the roll' changes the meaning).
- Confusing 'on a roll' with 'on a role' (homophone error).
