Mảng (autonym: [maŋ35]; Chinese: 莽语; pinyin: Mǎngyǔ) is an Austroasiatic language of Vietnam, China, and Laos.
In China, the Mảng people are also called Chaman (岔满), Abi (阿比), Mengga (孟嘎), Bageran (巴格然), and Mo (莫).
In Lai Châu Province, Vietnam, Mảng is spoken by 2,200 people in the districts of Sìn Hồ, Mường Tè, Phong Thổ, and in other nearby areas,[2] including in Nậm Ban Township, Sìn Hồ District, Lai Châu Province.
The Jinping County Gazetteer from the Republic of China period lists 12 Mảng villages: Gongdaniu (公打牛[6]), Luowuzhai (落邬寨), Pinghe (坪河, in Xiazhai 下寨,[7] Zhongzhai 中寨,[8] Shangzhai 上寨), Hetouzhai (河头寨), Guanmuzhai (管木寨), Naxizhai (纳西寨), Bianjiezhai (边界寨), Longshuzhai (龙树寨), Caoguoping (草果坪), and Nanke (南科[9]).
However, unlike surrounding Kra-Dai and Hmong-Mien languages which are entirely absent of inflections, Mảng retains Austroasiatic derivational morphology and case-marking on nouns.
