This Web site is devoted to lexpionage, the sleuthing of new words and phrases. These aren't "stunt words" or "sniglets," but new terms that have appeared multiple times in newspapers, magazines, books, Web sites, and other recorded sources.
WordNet® is an online lexical reference system whose design is inspired by current psycholinguistic theories of human lexical memory. English nouns, verbs, adjectives and adverbs are organized into synonym sets, each representing one underlying lexical concept. Different relations link the synonym sets.
There are many sites on the Internet with interactive dictionaries and language learning aids; there are also several freeware dictionary/flashcard programs with extensive vocabulary sets. However, in most cases, these sites shroud their data sets in binary or database formats. At Wordgumbo we've done the hard work of converting these data sets into flat files and posting them in one convenient archive, organized by language family.
