Nuosu or Nosu (, 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: ) 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 Nuòs? y? (simplified Chinese: ; traditional Chinese: ).[2]

The occasional terms 'Black Yi' (; h?i Yí) and 'White Yi' (; bái Yí) are castes of the Nuosu people, not dialects.[]

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 hold only 25% to 50% of their vocabulary in common. They share a common traditional writing system, though this is used for shamanism rather than daily accounting.[]

Dialects of Nuosu

Lama (2012)

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

  • Nuosu
    • Qumusu (Tianba)
    • Nuosu proper
      • Nuosu
        • Muhisu
        • Nuosu (nsu?)
          • Yinuo
          • Shengzha
      • Niesu (nie?su?)
        • Suondi
        • Adu

The Qumusu (Tianba ) dialect is the most divergent. The other dialects group as Niesu (Suondi and Adu) and as Nuosu proper (Muhisu , Yinuo , and Shengzha ). Niesu has lost voiceless nasals and has developed diphthongs.[3]

Adu , characterized by its labial-velar consonants, is spoken in Butuo County and Ningnan County of Liangshan Yi Autonomous Prefecture, Sichuan province, and also in parts of Puge County , Zhaojue County , Dechang County , and Jinyang County (Pan 2001).[4]

Nyisu or Yellow Yi of Fumin County, Yunnan may either be a Suondi Yi (Nuosu) dialect or Nisu dialect.

Zhu & Zhang (2005)[5] reports that the Shuitian people () reside mostly in the lowlands of the Anning River drainage basin, in Xichang, Xide, and Mianning counties of Liangshan Prefecture in Sichuan. They are called Muhisu (mu33 hi44 su33) by the neighboring Yi highland people. Shuitian is spoken in the following locations. Shuitian belongs to the Shengzha dialect () of Northern Yi.

Bradley (1997)

According to Bradley (1997),[7] there are 3 main dialects of Nosu, of which the Southeastern one (Sondi) is most divergent.

  • Northern
    • Tianba AKA Northwestern
    • Yinuo AKA Northeastern
  • Central (Shengzha )
  • Southeastern (Sondi)
    • Sondi
    • Adur

Chen (2010)

Chen (2010) lists the following dialects of Nosu. Also listed are the counties where each respective dialect is spoken.

  • Nosu ?
    • Senza, Shèngzhà
      • Senza, Shèngzhà (no?33 su33): 1,200,000 speakers primarily in Xide, Yuexi, Ganluo, Jinyang, Puge, Leibo, Xichang, Dechang, Mianning, Yanyuan, Yanbian, Muli, Shimian, Jiulong, and Luding; also in Huaping, Yongsheng, Ninglang, Lijiang, Jianchuan, Yongshan, and Qiaojia
      • Yino, Yìnuò (no?22 su22): 600,000 speakers primarily in Meigu, Mabian, Leibo, and Ebian, Ganluo; also in Yuexi, Zhaojue, and Jinyang
      • Lidim, Tiánbà (no?33 su33): 100,000 speakers primarily in Ganluo, Yuexi, and Ebian; also in Hanyuan
    • Sodi, Su?dì (no?33 su33): 600,000 speakers primarily in Tuoxian, Huili, Huidong, Ningnan, Miyi, Dechang, and Puge

Writing system

Classic Yi is a syllabic logographic system of 8,000–10,000 glyphs. Although similar to Chinese characters in function, the glyphs are independent in form, with little to suggest a direct relation.

The Modern Yi script (? nuosu bburma [ns? bm?] 'Nosu script') is a standardized syllabary derived from the classic script in 1974 by the local government of China. It was made the official script of the Yi languages in 1980. There are 756 basic glyphs based on the Liangshan dialect, plus 63 for syllables only found in Chinese borrowings.

In 1958 the Chinese government had introduced a Roman-based alphabet based on the romanized script of Gladstone Porteous of Sayingpan.[8] (This was later replaced by the Yi script.)

Nuosu has five pairs of phonemic vowels, contrasting in a feature Eatough calls loose throat vs. tight throat. Underlining is used as an ad-hoc symbol for tight throat; phonetically, these vowels are laryngealized and/or show a retracted tongue root. Loose vs. tight throat is the only distinction in the two pairs of syllabic consonants, but in the vocoids it is reinforced by a height difference.

The syllabic consonants y(r) u(r) are essentially the usual Sinological vowels ? ?, so y can be identified with the vowel of the Mandarin ? "four", but they have diverse realizations. Y(r) completely assimilates to a preceding coronal except in voice, e.g. /?z/ [] ? xyp "to marry", and are [m?l?] after a labial nasal, e.g. /m?zsz/ [m?m?ls] hmy sy "cloth". U(r) assimilates similarly after laterals, retaining its rounding, e.g. /l?v/ [l?l] ? hlu "to stir-fry", and is [m] after a labial nasal, e.g. /m?v/ [m?m] ? hmu "mushroom"; moreover it induces a labially trilled release of preceding labial or alveolar stops, e.g. /?dv?/ [?d??] ? ndup "to hit".

The tight-throat phone [] occurs as the realization of // in the high tone. That it is phonemically loose-throat is shown by its behaviour in tightness harmony in compound words.

Nuosu syllable structure is (C)V.


  • high [?] - written -t
  • high-mid [?] or mid falling [] - written -x (written with diacritic ? over symbol in the syllabary)
  • mid [?] - unmarked
  • low falling [] - written -p

The high-mid tone is only marginally contrastive. Its two main sources are from tone sandhi rules, as the outcome of a mid tone before another mid tone, and the outcome of a low-falling tone after a mid tone. However, these changes do not occur in all compounds where they might: for instance ? wo "bear" + ? mop "mother" regularly forms wo mox "female bear", but ? vi "jackal" + ? mop "mother" forms vi mop "female jackal" without sandhi. The syntax creates other contrasts: tone sandhi applies across the boundary between object and verb, so is present in SOV clauses like mu jy lu ti shex "Mujy looks for Luti", but is absent in OSV clauses like mu jy lu ti shep "Luti looks for Mujy". A few words, like ? xix "what?", have underlying high-mid tone.

Vocabulary and grammar

Nuosu is an analytic language, the basic word order is Subject-object-verb. Vocabularies of Nuosu can be divided into content words and function words. Among content words, nouns in Nuosu do not perform inflections for grammatical gender, number, and cases, classifiers are required when the noun is being counted; verbs do not perform conjugations for its persons and tenses; adjectives are usually placed after the word being fixed with a structural particle and do not perform inflections for comparison. Function words, especially grammatical particles, have a significant role in terms of sentence constructions in Nuosu. Nuosu does not have article words, but conjunctions and postposition words are used.[9]


Classifiers are required when numbers are used for fixing nouns.
