Discourse analysis is the study of language in use and how it constructs meaning and social interactions. It can analyze various text types like conversations and media. Discourse analysis examines linguistic features and how language relates to social context. Critical discourse analysis takes a more critical approach, explicitly analyzing power dynamics and how language can legitimize or challenge social inequalities. It aims to uncover hidden power structures in language used in politics, media, and other domains. While discourse analysis broadly studies language use, critical discourse analysis specifically investigates the role of language in shaping power relations and ideologies.
