“Nonce” is a word with more than one meaning, but in everyday English it is most often used to mean something done for a single time or a one-time purpose. In some contexts, especially in computing and security, it refers to a number used only once.
People use “nonce” mainly in technical or formal settings. In computer security, a nonce helps make a process unique and harder to fake or repeat. In older British English, the word can also mean “for the moment” or “for this specific occasion.”
