Japonic languagesJaponic or Japanese–Ryukyuan, sometimes also Japanic, is a language family comprising Japanese, spoken in the main islands of Japan, and the Ryukyuan languages, spoken in the Ryukyu Islands. The family is universally accepted by linguists, and significant progress has been made in reconstructing the proto-language. The reconstruction implies a split between all dialects of Japanese and all Ryukyuan varieties, probably before the 7th century. The Hachijō language, spoken on the Izu Islands, is also included, but its position within the family is unclear.
Ryukyuan languagesThe Ryukyuan languages, also Lewchewan or Luchuan (lu:'tSu:@n), are the indigenous languages of the Ryukyu Islands, the southernmost part of the Japanese archipelago. Along with the Japanese language and the Hachijō language, they make up the Japonic language family. Although Japanese is spoken in the Ryukyu Islands, the Ryukyu and Japanese languages are not mutually intelligible.
Ryukyuan peopleThe Ryukyuan people (Ruuchuu minzuku or Duuchuu minzuku, Ryūkyū minzoku, also Lewchewan or Loochooan) are a Japonic-speaking East Asian ethnic group native to the Ryukyu Islands, which stretch between the islands of Kyushu and Taiwan. Administratively, they live in either the Okinawa Prefecture or the Kagoshima Prefecture within Japan. They speak one of the Ryukyuan languages, considered to be one of the two branches of the Japonic language family, the other being Japanese and its dialects.
Ryukyu IslandsThe Ryukyu Islands also known as the Nansei Islands or the Ryukyu Arc, are a chain of Japanese islands that stretch southwest from Kyushu to Taiwan: the Ōsumi, Tokara, Amami, Okinawa, and Sakishima Islands (further divided into the Miyako and Yaeyama Islands), with Yonaguni the westernmost. The larger are mostly volcanic islands and the smaller mostly coral. The largest is Okinawa Island. The climate of the islands ranges from humid subtropical climate (Köppen climate classification Cfa) in the north to tropical rainforest climate (Köppen climate classification Af) in the south.
