Abstract: This study conducts a Critical Discourse Analysis (CDA) of Donald Trump’s 2025 Presidential Inaugural Address, aiming to uncover the linguistic, rhetorical, and ideological mechanisms through which the speech constructs political meaning. Drawing on Norman Fairclough’s three-dimensional CDA framework—textual analysis, discursive practice, and social practice—the research situates the inaugural address within the broader context of post-2020 U.S. political polarization, Trump’s return to office, and the ongoing contestation of national identity.
