Language of fictional superstate Oceania in 1949 George Orwell novel Nineteen Eighty-Four (8)
I believe the answer is:
newspeak
(Other definitions for newspeak that I've seen before include "Propaganda language in nineteen eighty-four" , "Language of 1984 (Orwell)" , "Orwell's nineteen eighty four language" , "fictional language" , "tongue used to spin?" .)
