Buyang (Chinese: 布央语) is a Tai–Kadai language spoken in Guangnan and Funing counties, Yunnan Province, China by the Buyang people. It is important to the reconstruction of Austro-Tai as it retains the disyllabic roots characteristic of Austronesian languages. Examples are /matɛ́/ "to die", /matá/ "eye", /qaðù/ "head", and /maðû/ "eight". (See Austro-Tai for proposed connections.) The Buyang language was only discovered in 1990 by Chinese linguist Liang Min. In 1999, a doctoral dissertation and book was published for Buyang. The book has also recently been translated into English.
