The Ryukyus (generally called Ruuchuu in the local dialects) with the central island of Okinawa (Uchinaa) are inhabited by people whose tongue is a very curious idiom which some linguists regard as an extreme branch of southern Japanese dialects. It seems, however, more correct to specify it as a separate language and the only language relative to Japanese. A survey of its fusional features will serve to support this claim, as they are of a much more radical nature and interfere with the fundamental character of the language much more than is the case with mainland Japanese.
