Northern Loloish languages

The Northern Loloish languages, also known as Northern Ngwi, are a branch of the Loloish languages that includes the literary standard of the Yi people. In Lama's (2012) classification, it is called "Nisoid" ("Nisu–Lope"), which forms the Nisoish branch together with the "Axi-Puoid" (Southeastern Loloish) languages.
Languages.
Two of the six Yi languages ("fangyan" 方言) officially recognized by the Chinese government belong to the Northern Loloish branch.
Another officially recognized Yi language ("fangyan"), Southern Yi (Nisu 尼苏), may or may not be a Northern Loloish language, as Pelkey (2011) classifies it as a Southeastern Loloish language based on phonological innovations shared with Southeastern instead of Northern Loloish languages.
Other Northern Loloish languages are listed below.
Nisu is classified as Southeastern Loloish by Pelkey (2011), but is traditionally classified as a Northern Loloish language.
Bradley (1997) also lists the endangered Kathu and Mo'ang languages of Wenshan Prefecture, Yunnan, China as Northern Loloish languages, but they were later classified as Mondzish by Lama (2012) and Hsiu (2014).
Bradley (2007).
Within Northern Loloish, David Bradley (2007) recognizes the "Nosoid" and "Nasoid" subgroups. Lama (2012) also recognizes a distinction between the Nuosu and Nasu clusters, with the Nuosu cluster including Nuosu and Niesu, and the Nasu cluster include Nasu, Gepu, and Nesu.
Samei, Samataw, and Sanie are classified as Nasoid by Bradley (2007), but as Kazhuoish languages by Lama (2012).
