Dialects
The Qumusu 曲木苏 (Tianba 田坝) dialect is the most divergent. 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). Niesu (distinguish Nesu) has lost the voiceless nasals and has developed a couple diphthongs.
The Yellow Yi (黄彝) of Kunming, central Yunnan, who call themselves Nisu, also speak a Northern Yi dialect (Bradley 2005). The Yellow Yi had originally migrated from Sichuan, and live in 4 villages in northwestern Fumin County (endangered) and 1 village in northwestern Anning County (moribund, highly endangered). It is most closely related to Suondi Yi (Bradley 2005).
