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 building bridges to neighbouring fields such as neuroscience and cognitive science. The series 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.

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.
