The document summarizes Norman Fairclough's dialectical-relational approach to critical discourse analysis (CDA). It outlines Fairclough's three-dimensional framework for analyzing discourse as text, discursive practice, and social practice. For each dimension, Fairclough proposes specific analytical categories and concepts, including textual analysis of vocabulary, grammar, cohesion and structure; discursive analysis of utterance force, text coherence and intertextuality; and social analysis of the relationship between discourse and power/ideology. The document provides an overview of Fairclough's influential work developing CDA and his dialectical theory of discourse.
