Controlled English

In the 1949 dystopian novel Nineteen Eighty-Four (also published as 1984), by George Orwell, Newspeak is the fictional language of Oceania, a totalitarian superstate. To meet the ideological requirements of Ingsoc (English Socialism) in Oceania, the Party created Newspeak, a controlled language of simplified grammar and restricted vocabulary designed to prevent people from being able to think critically. The Newspeak language thus limits the person's ability to articulate and communicate abstract concepts, such as personal identity, self-expression, and free will, which are thoughtcrimes, acts
