nonce
LowFormal / Technical
Definition
Meaning
Something created, coined, or used for a single, specific occasion or purpose.
A word, term, or phrase invented for immediate use, often for humour, clarity, or to fill a temporary lexical gap. In computing and cryptography, it refers to a number or string used only once in a communication.
Linguistics
Semantic Notes
The word has two distinct, unrelated senses: 1) A linguistic term for a one-off coinage. 2) A technical term in cryptography/security for a single-use value. The word is not related to the homograph in British slang.
Dialectal Variation
British vs American Usage
Differences
The British slang homograph for a sex offender is extremely rare and stigmatised in US usage; the technical/linguistic senses are identical in both varieties.
Connotations
In linguistics/computing, it is neutral and technical. In unrelated UK slang (a different word with the same spelling), it is highly pejorative and offensive.
Frequency
The technical/linguistic sense is infrequent but stable in both varieties. Awareness of the unrelated offensive slang sense is significantly higher in the UK.

Common Pitfalls
Translation Traps (for Russian speakers)
- Не переводить как "одноразовый" в бытовом контексте (better: 'одноразовый' или 'одноразовое слово/число').
- Полностью избегать прямых переводов из-за омонима с британским сленгом. Использовать описательные термины: "слово, созданное для конкретного случая" или "криптографический одноразовый номер".
Common Mistakes
- Using it in general conversation where 'temporary' or 'one-off' would be clearer.
- Pronouncing it to rhyme with 'pons' (should be like 'sconce').
- Assuming the technical sense is related to the offensive UK slang sense.

FAQ
Frequently Asked Questions
No, it is a low-frequency word used primarily in specialised academic or technical contexts like linguistics and cryptography.
Because in British English, an identical spelling is used as a highly offensive slang term for a sex offender, creating a high risk of misunderstanding or causing offence if used inappropriately.
A nonce word is created for immediate, one-time use with no expectation of entering the language. A neologism is a new word or phrase that gains some level of acceptance and ongoing use within a community.
It is an archaic or literary phrase meaning 'for the present time' or 'temporarily' (e.g., 'We'll use this solution for the nonce'). It is unrelated to the modern technical senses.
