... probably not. Another word to avoid is ‘niggardly’ even though it means ‘stingy’ or ‘meagerly’.
Vocabulary is getting so pathetic that if you use more than the basic 250 or so words in normal conversation, you get called names.
From 1984:
By curtailing frivolous and "fighting" words, the Party seeks to narrow the range of thought altogether, such that eventually, thoughtcrime will be literally impossible. "By 2050, earlier, probably - all real knowledge of Oldspeak will have disappeared. The whole literature of the past will have been destroyed. Chaucer, Shakespeare, Milton, Byron - they'll exist only in Newspeak versions, not merely changed into something different, but actually changed into something contradictory of what they used to be. Even the literature of the Party will change. Even the slogans will change. How could you have a slogan like 'freedom is slavery' when the concept of freedom has been abolished? The whole climate of thought will be different. In fact there will be no thought, as we understand it now. Orthodoxy means not thinking - not needing to think. Orthodoxy is unconsciousness."
