Nuosu language

Nuosu or Nosu (ꆈꌠꉙ or written in traditional script, transcribed as Nuo su hxop), also known as Northern Yi, Liangshan Yi, and Sichuan Yi, is the prestige language of the Yi people; it has been chosen by the Chinese government as the standard Yi language (Chinese: 彝语) and as such is the only one taught in schools in both oral and written forms. It was spoken by two million people and was increasing (as of PRC census); 60% were monolingual (1994 estimate). Nuosu is the native Nuosu name for their own language and is not used in Mandarin Chinese, though it may sometimes be translated as Nuòsūyǔ (simplified Chinese: 诺苏语; traditional Chinese: 諾蘇語).

The occasional terms "Black Yi" (黑彝; hēi Yí) and 'White Yi' (白彝; bái Yí) are castes of the Nuosu people, not dialects.^{[citation needed]}

Nuosu is one of several often mutually unintelligible varieties known as Yi, Lolo, Moso, or Noso. The six Yi languages recognized by the Chinese government have only 25% to 50% of their vocabulary in common. They share a common traditional writing system, but that is used for shamanism, rather than daily accounting.^{[citation needed]}

According to the Encyclopedia Britannica, it is one of the eight Tibeto-Burman languages with over 1,000,000 speakers (others being Burmese, Tibetan, Meitei, Bai, Karen, Hani, Jingpo).

Nuosu is mainly spoken in the Liangshan Yi Autonomous Prefecture, Sichuan.

There are other parts of Sichuan where Yi is spoken, including Panzhihua and Leshan.

In Yunnan, Northern Yi (Nuosu) is spoken in the north.

Lama (2012) gives the following classification for Nuosu dialects.
