This document discusses language identity, power, and politics. It defines identity as something that is constantly negotiated through interactions. There are four types of identity: master, interactive, personal, and relational. Language plays a role in national and cultural identity. The relationship between language and identity involves complex individual, social, and political factors. Power can be political, economic, or military. Language is one way that power is exercised through persuasion, regulation, inducement, or force. Politicians use language techniques like presupposition, implicature, metaphors, and euphemisms. English emerged as a language of power in Britain's colonies through imperial rule.
