Critical discourse analysis (henceforth CDA) is a transdisciplinary form of analysis (Fairclough, 2010) that “analyzes opaque as well as transparent structural relationships of dominance, discrimination, power and control as manifested in language” (Wodak & Meyer, 2002, p. 10). Compared with traditional discourse analysis which focus on discourse description and explanation with no or limited references to ideological practices and social power relations, CDA makes itself distinctive in that it dives deep into language and uncovers the underlying ideologies and social power structures which might be hard to notice. In general, relations hidden in language are the projections of social relations of language users in their real life. Therefore, CDA is of great practical importance in that it provides a window for comprehending the real social life of people and based on that, political actions can be motivated to “bring about radical and emancipatory social change” (Hammersley, 1997, p. 238). As Fairclough (2010) has pointed out, “the ultimate aim of CDA is to interpret and explain the social relationships embedded in language/discourse so as to facilitate righting or mitigating the social wrongs” (p. 4).
