Newspeak

Newspeak is a fictional variant of the English language, from George Orwell's dystopian novel Nineteen Eighty-Four. In the book, imposition of Newspeak systematically enforces the "IngSoc" totalitarian ideology, as it is "a medium of expression for the world-view and mental habits proper to the devotees of IngSoc, but [used] to make all other modes of thought impossible." The word can be used to mean any kind of "propagandistic language marked by euphemism, circumlocution, and the inversion of customary meanings".
