Fairclough's Critical Discourse Analysis is a disciplinary
method of written and spoken texts that sees language as a form of
social practice and focuses on how social and political domination
are constructed, reproduced or challenged by text or talk.
Fairclough evaluated a three dimensional framework for studying
discourse, where the target is to work with three different
analysis: analysis of language texts, analysis of discourse
practice and analysis of discursive.
Fairclough set up the rules of Critical Disclosure Analysis:
CDA solves social problems, power relations are discursive,
discourse includes society and culture and discourse does work
ideologically.
