PreDictionary 

PreDictionary n (pre, from Lat. prae, before + dictionary; or: predict + suffixes –ion and –ary) – a proactive dictionary that does not register words that are already in use but "predicts" new words, introduces them for the first time into common usage.

Almost all dictionaries, even those that contain neologisms, are reactive: they reflect various stages in the development of language. PreDictionary is a projective and proactive dictionary: it contributes new words that could make their way into the dictionaries of the future.
