A word that occurs only a single time within an entire text, a specific author's complete literary corpus, or the surviving records of a language.
From Ancient Greek ἅπαξ λεγόμενον (hápax legómenon, 'spoken once'). In textual scholarship and corpus linguistics, a hapax legomenon is a unique lexical singularity. In the works of William Shakespeare (which encompass 884,647 total words), there are over 7,000 hapax legomena—words that the Bard penned in only one single play or sonnet and never uttered again! The most famous Shakespearean hapax is the 27-letter tongue-twister 'honorificabilitudinitatibus' in Love's Labour's Lost. Other celebrated single-occurrence words include 'unaccommodated' (King Lear), 'bodkin' (Hamlet's bare dagger), 'mobled' (Hamlet's mobled queen), and 'kickshaws' (Twelfth Night). In biblical scholarship, hapax legomena pose famous translation dilemmas because there are no parallel passages to confirm their exact meaning.
