The article is devoted to the study of structural and semantic features of the main speech genre of presidential rhetoric — the inaugural speech. We characterized the main approaches to defining the speech genre and highlighted the structural components of the inaugural speech in political discourse. The purpose of the study is to reveal the structural and semantic features of the presidents’ inaugural speeches presented in Slavic languages (Ukrainian, Polish, Slovak and Serbian). The object of the research is the presidential discourse implemented in the speech activity of the presidents of Ukraine, Poland, Slovakia and Serbia. The subject of the study is the structural components and semantic features of the inaugural speeches in the presidential discourse. We analyzed the inaugural speeches of the presidents who held this position in the first half of 2024: Volodymyr Zelensky (Ukraine), Andrzej Duda (Republic of Poland), Zuzana Čaputová (Slovak Republic), Aleksandar Vučić (Republic of Serbia). The material for the analysis was the texts of the inaugural speeches delivered by the presidents in the last term. The methods of component and linguistic stylistic analysis were used to analyze the structural and semantic features of the inaugural speeches. The component analysis made it possible to consider the lexical semantics, and the linguistic stylistic analysis became the basis for determining the stylistic features of the texts. The structure of the inaugural speech covers the framework elements of the greeting, conclusion, formulation of the political creed. Speech acts of thanksgiving are the main structural elements of the inaugural speech of the presidents. At the semantic level, the inaugural speech contains a description of the political situation in the country in the context of historical events and a specification of program provisions of a priority nature. Common elements for the inaugural speeches of the presidents of Ukraine, Poland, Slovakia and Serbia are the presence of mandatory structural elements, the dominance of speech acts of thanksgiving, appeals to the historical past and the formulation of future political steps. Among the specific features of presidential speeches, the use of ethnonyms in the speeches of V. Zelenskyi and A. Duda was recorded; the dominance of references to ancient history in the speeches of A. Duda and O. Vuchich; V. Zelenskyi’s criticism of the previous government, in particular the country’s presidents.
