Kam–Sui languages

The Kam–Sui branch includes about a dozen languages. Solnit (1988) considers Lakkia and Biao languages to be sister branches of Kam–Sui, rather than part of Kam–Sui itself. The best known Kam–Sui languages are Dong (Kam), with over a million speakers, Mulam, Maonan, and Sui. Other Kam–Sui languages include Ai-Cham, Mak, and Tʻen, and Chadong, which is the most recently discovered Kam–Sui language. Yang (2000) considers Ai-Cham and Mak to be dialects of a single language. Thurgood (1988) Graham Thurgood (1988) presents the following tentative classification for the Kam–Sui branch. Chadong, a language that has been described only recently by Chinese linguist Jinfang Li, is also included below. It is most closely related to Maonan. Cao Miao and Naxi Yao, which are closely related to Southern Dong, have also been added from Shi (2015). • Kam-–ui • Mulam • Northern Kam–Sui • Kam • Macro-Sui • ''T'en'' • Greater Sui • Sui • Para-Sui • Chadong • Maonan • Ai-Cham/Mak • Ai-Cham • Mak ==Demographics==

Nearly all speakers of Kam–Sui languages originate in the Qiandongnan (Dong) and Qiannan (Sui, Then, Mak, Ai-Cham) Prefectures of Guizhou, as well as the prefecture-level cities of Hechi (Mulam and Maonan) and Guilin (Chadong) in northern Guangxi. Many Kam–Sui speakers have also migrated to farther urban areas such as Guangzhou. Small groups of Kam and Sui speakers also reside in Tuyên Quang Province, Vietnam, in the villages of Đồng Mộc and Hồng Quang, respectively.

The following language varieties are closely related to, or part of, Southern Dong. • Mjuniang 谬娘 or Cao Miao 草苗 (ISO 639-3: cov): 60,000 (1991) in Liping, Tongdao, and Sanjiang; closely related to Dong. Speakers are classified as ethnic Miao. • Naxi Yao 那溪瑶 (autonym: mu2 ɲiu1) is spoken by 2,500 people in Naxi Township 那溪瑶族乡, Dongkou County, Hunan Province, China. • Diao 调 (刁人): 2,000 (1999) in southeastern Guizhou around Liping and Congjiang; may speak Chinese or Dong. Speakers are classified as ethnic Dong. Diao (tjau13) is a Cao Miao subgroup according to Shi (2015:43). • Xialusi 下路司: 3,000 (1999) in southeastern Guizhou; classified as Dong, but their linguistic affiliation is unknown (possibly Kam-Sui). Speakers are classified as ethnic Dong. • Shui of Yunnan: 6,800 (1990) in Huangnihe 黃泥河 and Gugan 古敢水族乡, Fuyuan County, Yunnan; 490 (1990) in Dahe and Long'an of Yiliang County. In Gugan, there is a village cluster known as the "Five Shui Villages" 水五寨, consisting of Buzhang 补掌, Dongla 咚喇, Reshui 热水, Dazhai 大寨, and Duzhang 都章. It is still spoken in Xinbao Village 新堡村, Laochang Township 老厂乡, Fuyuan County, Yunnan. Also in Dacunzi 大村子, Geyi Township 格宜镇, Xuanwei City. However, these are actually all Northern Tai languages (Bouyei) according to Hsiu (2013). There are also some languages in southeastern Guizhou, northern Guangxi, and southwestern Hunan that have been influenced by Kam–Sui languages, such as Suantang 酸汤 and Tongdao Pinghua, a Pinghua lect spoken in Tongdao Dong Autonomous County, Hunan. Kam–Sui languages are also in contact with Suantang 酸汤, a Sinitic language spoken by about 80,000 ethnic Miao in Baibu 白布, Dihu 地湖, Dabaozi 大堡子, and Sanqiao 三锹 in Tianzhu, Huitong, and Jing counties (Chen Qiguang 2013:35). Suantang is very similar to New Xiang (新湘语), but is unintelligible with Southwestern Mandarin. ==Reconstruction==
