The following research aims to emphasize the significance of neologisms that emerge as a result of the war by the Russian Federation against Ukraine and their effect on the current Ukrainian media discourse. The purpose of the research is to identify the neologisms’ structure and semantics and explicate the reasons for their occurrence in the Ukrainian media discourse and vocabulary. Neologisms are created to name novel concepts or rename the already existing ones in different fields of life due to various changes caused by numerous factors. The methods used to analyze the corpus included linguistic analysis, linguo-cultural, word-forming analysis, and discourse analysis. The study concluded that neologisms were created to name people, countries, nations, as well as new concepts. Metonymy, metaphor and compounding were determined to be the most productive means of neologisms coinage in Ukrainian. Shortening, blending, misspellings, mishearings, mistranscriptions or mispronunciations turned out to be less productive in the Ukrainian language.
