Nuosu or Nosu (ꆈꌠꉙ, 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, both in its 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/Yi name for their own language and is not used in Mandarin Chinese, though it may sometimes be translated as Nuòsū yǔ (simplified Chinese: 诺苏语; traditional Chinese: 諾蘇語).
