Central Siberian Yupik, (also known as Siberian Yupik, Bering Strait Yupik, Yuit, Yoit, "St. Lawrence Island Yupik", and in Russia "Chaplinski Yupik" or Yuk) is an endangered Yupik language spoken by the indigenous Siberian Yupik people along the coast of Chukotka in the Russian Far East and in the villages of Savoonga and Gambell on St. Lawrence Island. The language is part of the Eskimo-Aleut language family. In Alaska, it is estimated that fewer than 1000 of the 1200 residents of St. Lawrence Island speak the language, while, in Russia, approximately 200 speakers remain out of an ethnic population of 1,200. Dialects and subgroups Siberian Yupik has two dialects: Chaplino (Chaplinski) Yupik (Uŋazigmit) is spoken on the shores of Chukotka Autonomous Okrug in the Russian Far North, and St. Lawrence Island Yupik (Sivuqaghmiistun) is spoken on St. Lawrence Island, Alaska. Chaplino, or Uŋazigmit, is the largest Yupik language of Siberia (the second one is Naukan Yupik), and is named after the settlement of Уӈазиӄ (Ungaziq; or Old Chaplino in Russian). The word Ungazighmii / Уңазиӷмӣ (plural Ungazighmiit / Уңазиӷмӣт ) means "Ungaziq inhabitant(s)". People speaking this language live in several settlements in the southeastern Chukchi Peninsula (including Novoye Chaplino, Provideniya, and Sireniki), Uelkal, Wrangel Island, and Anadyr. The majority of Chaplino Yupik speakers live in the villages of Novoye Chaplino and Sireniki. In another terminology, these people speak Chaplino, and Ungazighmiit people speak one of its dialects, along with other dialects spoken by Avatmit, Imtugmit, Kigwagmit, which can be divided further into even smaller dialects. The second dialect, St. Lawrence Island Yupik, is believed to be an offspring of Chaplino with only minor phonetic, phonological, morphological, syntactical and lexical differences, and the two dialects are virtually identical. Phonology Consonants Unlike the Central Alaskan Yupik languages, Siberian Yupik has a series of retroflex fricatives, more similar to the Alaskan Inuit dialects. Vowels Morphosyntax Morphosyntax is the study of grammatical categories or linguistic units that have both morphological and syntactic properties. Central Siberian Yupik’s structure most resembles this category. In addition, CSY can be described as using both internal and external syntax. Internal syntax is used here to describe the way that postbases are added to a base or added to one another, contrasted with external syntax, which refers to the order of independent words. Central Siberian Yupik is a polysynthetic language, meaning it is made up of long, structured words containing
