The linguistic study of the Slavic language family, with its rich syntactic and phonological structures, complex writing systems, and diverse socio-historical context, is a rapidly growing research area. Bringing together contributions from an international team of authors, this Handbook provides a systematic review of cutting-edge research in Slavic linguistics. It covers phonetics and phonology, morphology and syntax, lexicology, and sociolinguistics, and presents multiple theoretical perspectives, including synchronic and diachronic. Each chapter addresses a particular linguistic feature pertinent to Slavic languages, and covers the development of the feature from Proto-Slavic to present-day Slavic languages, the main findings in historical and ongoing research devoted to the feature, and a summary of the current state of the art in the field and what the directions of future research will be. Comprehensive yet accessible, it is essential reading for academic researchers and students in theoretical linguistics, linguistic typology, sociolinguistics and Slavic/East European Studies.
