My Flashcards

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.

Watch out

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.
