Critical discourse analysis (CDA) aims to reveal hidden values and perspectives in language use. CDA explores the connection between language and its social/political contexts. Key principles of CDA are that social issues are constructed through discourse, power relations are negotiated in discourse, and ideologies are produced in discourse. CDA analyzes discourse genres, framing, multimodality, identity construction, and texts from the world wide web. Criticisms of CDA include that it does not sufficiently consider reader interpretation or provide systematic textual analysis.
