Bhutia language

The Sikkimese language, also called "Sikkimese Tibetan", "Bhutia", "Drenjongké" (Tibetan: འབྲས་ལྗོངས་སྐད་, Wylie: 'bras ljongs skad "Rice Valley language"), Dranjoke, Denjongka, Denzongpeke, and Denzongke, belongs to the Southern Tibetic languages. It is spoken by the Bhutia in Sikkim and northeast Nepal. The Sikkimese people refer to their own language as Drendzongké and their homeland as Drendzong (Tibetan: འབྲས་ལྗོངས་, Wylie: 'bras-ljongs; "Rice Valley").

Sikkimese is written using Tibetan alphabet, which it inherited from Classical Tibetan. Sikkimese phonology and lexicon differ markedly from Classical Tibetan, however. SIL International thus describes the Sikkimese writing system as "Bodhi style". According to SIL, 68% of Sikkimese Bhutia were literate in the Tibetan script in 2001.

Speakers of Sikkimese can understand some Dzongkha, with a lexical similarity of 65% between the two languages. By comparison, Standard Tibetan, however, is only 42% lexically similar. Sikkimese has also been influenced to some degree by the neighbouring Yolmowa and Tamang languages.
