key lime
LowCulinary, Informal
Definition
Meaning
A small, round, yellow-green citrus fruit (Citrus aurantifolia) that is notably aromatic and tart, originally cultivated in the Florida Keys.
Most commonly refers to the eponymous dessert, 'key lime pie,' but can describe any food or product (e.g., yogurt, candle) flavoured with the juice or essence of this fruit.
Linguistics
Semantic Notes
The term is a compound noun. Its primary association is gastronomic and regional (Florida). The 'key' refers to the Florida Keys, not a 'key' as in 'important.'
Dialectal Variation
British vs American Usage
Differences
The term is more widely known and used in American English due to the dessert's popularity and the fruit's geographic association. In British English, it is primarily a culinary loanword.
Connotations
In the US, strongly evokes Florida, sunshine, and the specific dessert. In the UK, it is more generic as an exotic fruit/flavour descriptor.
Frequency
Significantly more frequent in American English, especially in food contexts. Rare in everyday British discourse outside of specific foodie or recipe contexts.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation as 'ключевая известь' or 'ключевой лайм' which sounds nonsensical. Use established borrowing 'лайм' with specification 'Флоридский' or 'для пирога' if needed, e.g., 'лайм для пирога Кей-Лайм'.
- The word 'key' here is a geographical name, not the adjective 'key' meaning 'important' ('ключевой').
Common Mistakes
- Writing as one word: 'keylime' (should be two words or hyphenated: 'key-lime', especially when used attributively).
- Confusing it with the common Persian lime.
- Incorrect capitalisation: 'Key Lime' is standard when referring to the specific variety or pie.
