[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).

In Thailand, Nuosu (usually referred to as Lolo), is spoken in Chiang Rai Province.

The other dialects group as Niesu (聂苏, Suondi and Adu) and as Nuosu proper (Muhisu 米西苏, Yinuo 义诺, and Shengzha 圣乍).

Zhu and Zhang (2005)[6] reports that the Shuitian people (水田人) reside mostly in the lowlands of the Anning River drainage basin, in Xichang, Xide, and Mianning counties of Liangshan Prefecture in Sichuan.

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.

Y(r) completely assimilates to a preceding coronal except in voice, e.g. /ɕz̩˨˩/ [ɕʑ̩˨˩] ꑮ xyp "to marry", and is [m͡l̩] after a labial nasal, e.g. /m̥z̩˧sz̩˧/ [m̥m͡l̩˧sɹ̩˧] ꂪꌦ hmy sy "cloth".

The syntax creates other contrasts: tone sandhi applies across the boundary between object and verb, so is present in SOV clauses like ꃅꏸꇐꄜꎷ mu jy lu ti shex "Mujy looks for Luti", but is absent in OSV clauses like ꃅꏸꇐꄜꎹ mu jy lu ti shep "Luti looks for Mujy".

Although similar to Chinese characters in function, the glyphs are independent in form, with little to suggest a direct relation.

In 1958 the Chinese government had introduced a Roman-based alphabet based on the romanized script of Gladstone Porteous of Sayingpan.

There are 756 basic glyphs based on the Liangshan dialect, plus 63 for syllables only found in Chinese borrowings.

Function words, especially grammatical particles, have a significant role in terms of sentence constructions in Nuosu.
