Doublespeak is language that deliberately obscures, disguises, distorts, or reverses the meaning of words. Doublespeak may take the form of euphemisms, in which case it is primarily meant to make the truth sound more palatable. It may also refer to intentional ambiguity in language or to actual inversions of meaning.
Doublethink is a process of indoctrination whereby the subject is expected to simultaneously accept two mutually contradictory beliefs as correct, often in contravention of one's own memories or sense of reality. Doublethink is related to, but differs from, hypocrisy.
Political Slavespeak consists of "terrocrat" words—words that give terrocrats advantages over their victims; words that, if accepted, believed, and used, put victims at a disadvantage.
