Bolyu language

The Bolyu language (autonym: '; ; also known as Paliu, Palyu, or Lai''' 俫语, 徕语) is an Austroasiatic language of the Pakanic branch.

Classification
Bolyu is related to the Bugan language, forming the Pakanic branch along with it. In 1984, Bolyu was first studied by Liang Min of the Nationalities Research Institute in Beijing. Liang was the first to suggest a Mon–Khmer affiliation of Bolyu, which was later confirmed by Western linguists such as Paul K. Benedict, Paul Sidwell, and Jerold A. Edmondson. However, the place of the Pakanic branch within the Mon–Khmer family is uncertain. Sidwell (1995) suggests that the Pakanic branch may be an Eastern Mon–Khmer branch, thus making it most closely related to the Vietic branch. However, Gérard Diffloth classifies Pakanic as Northern Mon–Khmer, making it most closely related to the Palaungic branch. Paul Sidwell later classified Bolyu and Bugan together as forming a separate Pakanic branch within Austroasiatic, while Mang is excluded as yet another separate branch of Austroasiatic.
