transpire
C1Formal, Academic
Definition
Meaning
To occur or happen; to become known or apparent.
Originally meant (and is still used in botany/biology) to give off water vapor through pores (transpiration). The figurative meaning 'to happen' is now dominant, though sometimes considered incorrect by purists when used as a synonym for 'occur'.
Linguistics
Semantic Notes
The sense 'to happen' is common but may be criticized in very formal writing where 'occur' or 'take place' is preferred. The sense 'to become known/leak out' is less common. The biological sense is technical.
Dialectal Variation
British vs American Usage
Differences
Minor. The figurative meaning 'to happen' is slightly more accepted and frequent in American English, though still formal. British English may be slightly more likely to retain the 'leak out/become known' sense.
Connotations
Formality connotation is strong in both varieties. Using 'transpire' for 'happen' in casual speech can sound pretentious.
Frequency
Low-to-medium frequency in formal contexts. Rare in informal speech in both varieties.

Common Pitfalls
Translation Traps (for Russian speakers)
- False friend with 'транспирация' (biological term only).
- Do not directly translate as 'произойти' in all contexts—it's too formal.
- The 'become known' sense is closer to 'выяснилось', 'обнаружилось'.
Common Mistakes
- Using it as a fancier synonym for 'happen' in informal contexts.
- Confusing it with 'transpire' meaning 'to sweat' (which applies to plants, not people).
- Misspelling as 'transpire'.
