This book presents a sociocultural linguistic analysis of discourses of conflict, as well as an examination of how linguistic identity is embodied, negotiated and realized during a time of war. It provides new insights regarding multilingualism among Ukrainians in Ukraine and in the diaspora of New Zealand, the US and Canada, and sheds light on the impact of the Russian-Ukrainian war on language attitudes among Ukrainians around the world. Crucially, it features an analysis of a new movement in Ukraine that developed during the course of the conflict – ‘changing your mother tongue', which embodies what it is to renegotiate linguistic identity. It will be of value to researchers, faculty, and students in the areas of linguistics, Slavic studies, history, politics, anthropology, sociology and international affairs.
