The ruling doctrine of Oceania is Ingsoc, the Newspeak neologism for English Socialism. "Newspeak" is a simplified and obfuscatory language designed to make independent thought impossible. At one point, she flings a Newspeak dictionary at the telescreen. It is used to illustrate concepts such as propaganda, newspeak, and the totalitarian state. Many of the telescreen programmes are transmitted in Newspeak. The grammar of Newspeak is greatly simplifed compared to English. This is one of the key differences between Newspeak and Smalltalk. Newspeak is distinguished by its unusual approach to modularity. The Ministry of Plenty (Newspeak&colon; Miniplenty) is in control of Oceania's command economy. Similar arrangements are also possible in languages such as Self and Newspeak. The term "sexcrime" is one of several Newspeak words found within the novel. The Ministry of Love (Newspeak&colon; Miniluv) serves as Oceania's interior ministry. "The Principles of Newspeak" is an academic essay appended to the novel. Basic English later inspired his use of Newspeak in "Nineteen Eighty-Four". A later book, "Newspeak in the 21st Century", taking a similar approach, appeared in 2009.
