Newspeak is a fictional language created by George Orwell in his novel 1984. It is designed to limit freedom of thought and expression by reducing the complexity of language. The ultimate goal of Newspeak is to make it impossible to think critically or rebel against the totalitarian regime of Big Brother. The vocabulary of Newspeak is intentionally restricted, with many words eliminated or simplified. For example, the word 'bad' is replaced with 'ungood', and complex ideas are reduced to single terms. This manipulation of language serves as a tool for control, illustrating the power of words in shaping reality.
