Review of : Kiss, Nadiya, and Monika Wingender, editors. Contested Language Diversity in Wartime Ukraine: National Minorities, Language Biographies, and Linguistic Landscape. Ibidem-Verlag, 2025. The title of the volume Contested Language Diversity in Wartime Ukraine immediately speaks to the urgency and relevance of its content. In light of Russia’s full-scale invasion of Ukraine in 2022, questions surrounding language, identity, and power have intensified and gained new dimensions. Language has emerged not only as a cultural and communicative medium but also as a battleground for ideological and political confrontation. As language is increasingly perceived as a marker of allegiance, the shifting dynamics of linguistic practices in Ukraine call for rigorous academic investigation – an effort this volume undertakes with depth and breadth.
