Critical Discourse Analysis (CDA) is an interdisciplinary approach to the study of discourse, which views "language as a form of social practice" (Fairclough 1989: 20) and focuses on the ways social and political domination is reproduced by text and talk. CDA developed within several disciplines in the humanities and social sciences, such as 'critical linguistics'.
CDA is founded on the idea that there is unequal access to institutionally controlled linguistic and social resources. The patterns of access to discourse and communicative events is one essential element for CDA. Although CDA is sometimes mistaken to represent a 'method' of discourse analysis, it is generally agreed that any explicit method in discourse studies, the humanities and social sciences may be used in CDA research, as long as it is able to adequately and relevantly produce insights into the way discourse reproduces (or resists) social and political inequality, power abuse or domination. That is, CDA does not limit its analysis to specific structures of text or talk, but systematically relates these to structures of sociopolitical context.
