Lexicon-Cetus is a dictionary that compiles and defines every single unique word from Melville’s Moby-Dick; or, The Whale. There are approximately 16,000 “unique” words in Moby-Dick; about 5,000 of them are a mixture of common given names, plurals, infinitives, gerunds, and/or adjectival/adverbial forms of root words. If the root word is already defined in the lexicon, then any derivations thereof are for the most part excluded.
