This PhD dissertation analyzes Arundhati Roy's novel "The God of Small Things" using critical discourse analysis. The study uses Fairclough's Three Dimensional Framework and Hodge and Kress's syntagmatic and power models to analyze the various discourses within the novel, including social, gender, religious, caste, police, political, colonial, and post-colonial discourses. The dissertation consists of six chapters that introduce the study, review relevant literature, present the theoretical framework and analysis method, extract and identify discourses from the novel, analyze the discourses to reveal notions of power and injustice, and summarize the findings and recommendations.
