The scope and nature of the connections between the Transeurasian languages are among the most disputed issues in comparative historical linguistics. This four-volume collection will assemble the most important scholarly writings concerning the historical relationship between these languages, particularly those discussing areal and genealogical correlations.

This book deals with shared verb morphology in Japanese and other languages that have been identified as Transeurasian (traditionally: "Altaic") in previous research. It analyzes shared etymologies and reconstructed grammaticalizations with the goal to provide evidence for the genealogical relatedness of these languages.

TRENDS IN LINGUISTICS is a series of books that open new perspectives in our understanding of language. The series publishes state-of-the-art work on core areas of linguistics across theoretical frameworks, as well as studies that provide new insights by approaching language from an interdisciplinary perspective. TRENDS IN LINGUISTICS considers itself a forum for cutting-edge research based on solid empirical data on language in its various manifestations, including sign languages. It regards linguistic variation in its synchronic and diachronic dimensions as well as in its social contexts as important sources of insight for a better understanding of the design of linguistic systems and the ecology and evolution of language. TRENDS IN LINGUISTICS publishes monographs and outstanding dissertations as well as edited volumes, which provide the opportunity to address controversial topics from different empirical and theoretical viewpoints. High quality standards are ensured through anonymous reviewing.

The Oxford Guide to the Transeurasian Languages provides a comprehensive account of the Transeurasian languages, and is the first major reference work in the field since 1965. The term 'Transeurasian' refers to a large group of geographically adjacent languages that includes five uncontroversial linguistic families: Japonic, Koreanic, Tungusic, Mongolic, and Turkic. The historical connection between these languages, however, constitutes one of the most debated issues in historical comparative linguistics. In the present book, a team of leading international scholars in the field take a balanced approach to this controversy, integrating different theoretical frameworks, combining both functional and formal linguistics, and showing that genealogical and areal approaches are in fact compatible with one another. The volume is divided into five parts. Part I deals with the historical sources and periodization of the Transeurasian languages and their classification and typology. In Part II, chapters provide individual structural overviews of the Transeurasian languages and the linguistic subgroups that they belong to, while Part III explores Transeurasian phonology, morphology, syntax, lexis, and semantics from a comparative perspective. Part IV offers a range of areal and genealogical explanations for the correlations observed in the preceding parts. Finally, Part V combines archaeological, genetic, and anthropological perspectives on the identity of speakers of Transeurasian languages. The Oxford Guide to the Transeurasian Languages will be an indispensable resource for specialists in Japonic, Koreanic, Tungusic, Mongolic, and Turkic languages and for anyone with an interest in Transeurasian and comparative linguistics more broadly.
