In current society, language is not only a tool for communication, it also reflects and affects power relations and social structures. Critical discourse analysis (CDA), as a research method that focuses on revealing hidden social meanings, can interpret these hidden social inequalities. The essence of CDA is to view language as a social practice, exploring how language plays a role in shaping and maintaining power structures.
The purpose of critical discourse analysis is to reveal the interaction between language and social reality and to understand how power operates at different social levels through language.
The term critical discourse analysis first originated from critical linguistics at the University of East Anglia in the UK in the 1970s. Scholars in the field, notably Norman Fairclough and Ruth Wodak, introduced perspectives from social theory and critical theory, thus giving CDA a both linguistic and sociological perspective. CDA scholars believe that language use is inseparable from social structure and, to some extent, the two constitute each other.
CDA’s research methods include a variety of methods drawn from the humanities and social sciences. This requires approaches that develop a deep understanding of how discourse reproduces or resists social and political inequalities. For example, Stephen Theo raises the phenomenon of racial discrimination in sex reporting and describes how media language is used in mainstream media to influence public opinion.
In analysis, CDA not only focuses on the specific structure of a text or conversation, but also systematically links it to the sociopolitical context.
Critical discourse analysis has been widely used in fields as diverse as media studies, advertising content, English teaching, and environmental science. In political language, CDA helps examine how politicians' rhetoric manipulates public perception. For example, scholars have explored how the media engages in political manipulation during the legislative process to promote tougher laws without changing regulations.
The effectiveness of CDA is that it not only analyzes the language itself, but also participates in the interpretation and action of the results of this resource analysis.
In the field of critical discourse analysis, many scholars such as Fairclough, Wodak and Van Dijk have laid the foundation for this. The theoretical concepts they proposed, such as "language, power, ideology," etc., still have an impact on research in this field. In particular, Fairclough's three-dimensional analytical framework emphasizes the need to comprehensively consider the relationship between texts, discursive practices, and social and cultural backgrounds during analysis.
Through critical discourse analysis, we can gain a deeper understanding of how language becomes a tool for the demonstration of power and further reveal the roots of social inequality. In modern society, reflecting on the discourses we are exposed to on a daily basis, especially in the context of media and politics, will help us understand our own place and trigger the possibility of social change. However, facing the future, this question still deserves our deep thinking: How to use language to challenge the existing social inequality model?
