What is newspeak? What is Duckspeak?

Essentially, the Newspeak language was designed to limit the range of thought. Language was systematically purged of words that allow people to describe feelings and emotions. The result is a very sterile language that permits only facts and simple ideas. "Duckspeak" is an example of language destruction. Syme points out that duckspeak means, "to quack like a duck. It is one of those interesting words that have two contradictory meanings. Applied to an opponent, it is abuse; applied to someone you agree with, it is praise." Really there is no meaning to it other than to apply the same sounds to multiple situations.
