Diachrony of verb morphology: Japanese and Transeurasian languages, 2015:p. 4 (Stretching from the Pacific in the east to the Mediterranean and the Baltic in the west, the Transeurasion languages form a vast linguistic continuum that crosses the physical boundaries between Europe and Asia. Contrary to the tradition to refer to these languages as "Altaic languages," Johanson and Robbeets...coined the term "Transeurasian" to refer to this large group of geographically adjacent languages, which share a significant number of linguistic properties and include at most 5 linguistic families: Japanic, Koreanic, Tungusic, Mongolic, and Turkic.)
