Importance of Language; Newspeak.
It is the intention of the government to make it impossible to convey any nonconformist thoughts. Hence Newspeak was designed for this very intention. To narrow down what people can actually say and think, the rules of language are being skewed from what we actually say right now. Negative terms have been eliminated from the language. In Newspeak, "bad" and "awful" are altered to mean "ungood" or "doubleplus ungood." This language leaves no room for nuance or shades of meaning. It also shortens terms in order to make the language as simple as possible, as in "Thought Police" becoming "thinkpol." The influence of this language spreads out among the people to cull what they are actually thinking. Since language is the expression of ones thoughts, if the words you need to express your thoughts are no longer there, then you will simply cease to have those thoughts.
For future generations of Oceania, thoughts that the government didn't approve will no longer even be there because there will be no words to describe them.

For example, I remember how confused my parents were when the word "bad" actually meant "good." Another term used nowadays from the younger generations is...
