Siberian Yupik has two dialects: Chaplinski Yupik is spoken on the shores of the Chukchi Peninsula in the Russian Far North, and St. Lawrence Island Yupik (Sivuqaghmiistun) is spoken on St. Lawrence Island, Alaska. The majority of Chaplinski Yupik speakers live in the villages of Novoye Chaplino and Sireniki, on the coasts of the Chukchi Peninsula. St. Lawrence Island Yupik is believed to be an offspring of Chaplinski and apart from some few phonetic, phonological, morphological, syntactical and lexical peculiarities is practically identical with it.
Chaplino, or Ungazighmiistun, is the largest Yupik language of Siberia (the second one is Naukan), and is named after the settlement of Ungaziq (Novoye Chaplino). The word Ungazighmii / Уңазиӷмӣ [uŋaʑiʁmiː] (plural Ungazighmiit / Уңазиӷмӣт [uŋaʑiʁmiːt]) 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. 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.
Naukan, or Nuvuqaghmiistun, the second largest Yupik language spoken in Siberia, is spoken in settlements including Uelen, Lorino, Lavrentiya, and Provideniya.
Additionally, the Sireniki Eskimo language, locally called Uqeghllistun, was an Eskimo language once spoken in Siberia. It had many peculiarities. Sometimes it is classified as not belonging to the Yupik branch at all, thus forming (by itself) a stand-alone third branch of the Eskimo languages (alongside Inuit and Yupik). Its peculiarities may be the result of a supposed long isolation from other Eskimo groups in the past.
Sireniki became extinct in early January 1997.
