This book provides a comprehensive account of the discipline of Critical Discourse Analysis (CDA) and demonstrates multiple linguistic methods through which it exposes and demystifies ideologies that are present in institutional discourse. The book enables readers to critique the complexities of the relationship between language and power to expose the ideological operation of discourse. Proceeding from a theoretical grounding for CDA in contemporary society, the book comprises analysis of a wide range of discourse examples, including the news media, political speeches, public service leaflets and social media. Readers are guided through a diverse range of models in CDA in order to scrutinise and assess the role of language in society and to consider and challenge the principles of powerful networks, institutions and organisations.
