The impact of sociosemiotic perspective of language on the change of discourse model in Critical Discourse Analysis

Throughout his theoretical work, Norman Fairclough advocates for a significant shift in the concept of discourse, which has far-reaching implications for Critical Discourse Analysis as a whole, due in large part to his influential contributions to the field. In the book Discourse and social change (1992), the theorist describes discourse from a three-dimensional viewpoint. The term “discourse” is then re-examined in Discourse in late modernity: rethinking Critical Discourse Analysis (1999) by the same author in collaboration with Lilie Chouliaraki; they view discourse as an instance of social practice. This concept is further developed in Analyzing discourse: textual analysis for social research (2003). This bibliographical research aims to show how the conceptual change facilitated by Fairclough was shaped by Michael Halliday's sociosemiotic view of language, according to what language is a set of systems that interact with and are shaped by social life, situational context, and culture. In other words, “language in a social-semiotic perspective”, as Halliday and Systemic-Functional Linguistics set, is the point of this understanding. In summary, research into language under the framework of social-semiotic has distinguished Critical Discourse Analysis as a theoretical approach aimed at uncovering social issues through texts and facilitating social transformation through linguistic means. Studies and research have been impacted by this situation, particularly in Latin America, prompting investigations into social issues of primary concern, while also continuing to incorporate linguistic analysis and the effects of Systemic-Functional Linguistics.
