Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation as 'опухшая голова' — this is nonsensical for the idiom. The correct conceptual equivalent is 'зазнайство', 'высокомерие', or the idiom 'зарваться'.
- Do not confuse with 'головокружение от успехов' (dizziness from success), which is closer to 'go to one's head'.
Common Mistakes
- Using it literally (e.g., 'After the bee sting, he had a swollen head').
- Confusing it with 'swollen-headed' as an adjective (less common but possible).
- Misspelling as 'swollen-head' (hyphenated) when used as a noun phrase.
