Nadsat is a set of slang terms invented by Anthony Burgess in his 1962 novel A Clockwork Orange. The "slang of the future" used in the book has a variety of sources, most of the words being derived from Russian (many from bad transliterations of Russian as well). Other words have notably Germanic and Romance sources, some are abbreviations of English words, and some are forms of school-boy slang (or "potty talk") or Cockney rhyming slang. The name Nadsat itself is a Russian suffix for numbers 11-19 (equivalent to "teen" in the English numbering system). A doctor in the novel explains the slang as "odd bits of old rhyming slang", "A bit of gypsy talk, too." There are inconsistencies, however, in the use of the speech in the book when Alex forgets a word for something and instead uses a different one or makes up his own. Some words occur only as part of his idiolect.
Throughout the book Alex, the narrator and main character, thinks and speaks in Nadsat. The book is a difficult read the first time through due to the use of the slang terms, but context clues can help one to figure out what some of it means. The movie uncomplicates the language a little because there are visuals, but either way there may be quite a few mysterious terms for the everyday reader to figure out. For example, Alex says in one part of the novel: "But suddenly I viddied that thinking was for the gloopy ones and the oomny ones used like inspiration and what Bog sends... ". Below is a list of the words that are used in the novel that need defining, as well as the etymology of most of the words according to the author and related sources.

Credit where credit is due: This list has come a long way. Most of the words were originally individually noded by Pseudo_Intellectual. The re-formatting of about half the words as a list (as well as some research) was taken up by alex. I then finished re-formatting and researching what was left on the list and added the foreword explaining what it was. A number of words were added to the list in the course of research. If there are any discrepancies in the list (I know the book, but I don't know Russian) please /msg me. I will have a native speaker of Russian see the list shortly.
