The article presents the results of research aimed at defining the concept of "euphemism" and its role in modern political discourse. The study of euphemism is an urgent linguistic issue today, however, particular attention is devoted to the study of the phenomenon of euphemization in political discourse. Political euphemisms strongly influence public opinion by highlighting events and actions in a specific light. Official political speeches, as a means of communication between politicians and people, are especially important now during the period of Russian aggression against Ukraine. That is why the study was based on the speeches of three world leaders: U.S. President Joe Biden, Canadian Prime Minister Justin Trudeau, and Ukrainian President Volodymyr Zelenskyy. It is revealed that in the context of the Russo-Ukrainian war, political leaders used euphemisms to downplay or mitigate the seriousness of certain actions or events. The peculiarities of euphemism functioning in contemporary political discourse remain relatively unexplored and require further study and detailed analysis.
