"Newspeak" is a term originating from George Orwell's book titled "1984", in which Newspeak is a language spoken in the country of Oceania, used as a form of thought control. In short, the language gets rid of very words that allow rebellious thinking and often replaces them with good-sounding words, meaning that the populace is simply unable to think of dissent, making it impossible, or views bad things as good and desirable.
