So while perusing my dictionary, I found this gem of a word, meaning a word or form that occurs only once in the corpus of a given language.
How in the heck is this word used usefully? Is it only used with dead languages? Or does citing a “hapax legomena” in a living language not contribute to annulling that word’s hapax lemomenal status? Or do you say, “Until so-and-so a date, so-and-so word was a hapax legomena, but then so-and-so author cited it in a famous work and it has entered the popular lexicon since.”
