When using language, the speaker or writer should consider both sociocultural and functional aspects of language. Based on these dimensions the speaker or writer, considering contextual elements such as social, political, and cultural context, uses appropriate vocabulary, grammar, and discourse to fulfill the language function in an appropriate way in order to convey his/ her intention (Atkins, 2002). Schaffner (1996) said that any political action is prepared, accompanied and controlled, and influenced by language. Using Critical Discourse Analysis (CDA) helps us to uncover the latent meaning in a text behind special words and structure (Atkins, 2002). This paper has tried to figure out the theoretical underpinnings of CDA and its status from the past to the present.
