Miyako, Ishigaki, and Yonaguni, the Southern Ryukyuan languages
The Oxford Guide to the Transeurasian Languages
The Sakishima area in the southern Ryūkyūs consists of three main languages: Miyako (represented by Hirara, but with some data also drawn from Irabu), Ishigaki, and Yonaguni. While these three languages are mutually unintelligible, even a cursory examination demonstrates that these languages are related. After a brief outline to the historical connections, the phonology, morphology, syntax, and lexicon are described, comparing and contrasting data from these three languages. These languages are critical to a better understanding of the language history of the languages throughout the Japanese archipelago.
