In George Orwell's Nineteen Eighty-Four, the fictional language Newspeak attempts to eliminate personal thought by restricting the expressiveness of the English language.

In keeping with the principles of Newspeak, all of the words listed here serve as both nouns and verbs; thus, crimethink is both the noun meaning "thoughtcrime" and the verb meaning "to commit thoughtcrime". To form an adjective, one adds the suffix "-ful" (e.g., crimethinkful) and to form an adverb, "-wise" (e.g., crimethinkwise). There are some irregular forms, such as the adjectival forms of Minitrue, Minipax, Miniplenty, and Miniluv (Ministry of Truth, Ministry of Peace, Ministry of Plenty, and Ministry of Love, respectively – all ministries of the active government in Nineteen Eighty-Four).

To say that something or somebody is the best, Newspeak uses doubleplusgood, while the worst would be doubleplusungood (e.g., "Big Brother is doubleplusgood, Emmanuel Goldstein is doubleplusungood").

The word bellyfeel means a blind, enthusiastic acceptance of an idea. The word likely comes from the idea that any good Oceanian should be able to internalise Party doctrine to the extent that it becomes a gut instinct – a feeling in the belly.

Consider, for example, such a typical sentence from a Times leading article as "Oldthinkers unbellyfeel Ingsoc." The shortest rendering one could make of this in Oldspeak would be: "Those whose ideas were formed before the Revolution cannot have a full emotional understanding of the principles of English Socialism." But this is not an adequate translation. ... Only a person thoroughly grounded in Ingsoc could appreciate the full force of the word bellyfeel, which implied a blind, enthusiastic, and casual acceptance difficult to imagine today.
