nonce

What does "nonce" mean?
A "nonce" refers to something created or used for a single, specific occasion rather than for general, long-term use. Think of it as a "one-off" solution—like a temporary password generated just to get you through a single login, or a word invented by an author to fit the exact mood of a single paragraph. In linguistics, it is frequently used to describe "nonce words," which are neologisms coined for a specific context and rarely survive beyond that moment. It is a formal term, often used in computing (e.g., "nonce value") to describe a unique number used in security protocols to prevent replay attacks.
