Puyŏ languages
The Puyŏ (Korean: 부여; RR: Buyeo; MR: Puyŏ; Chinese: 扶餘; pinyin: Fúyú) or Puyo-Koguryoic languages are four languages of northern Korea and eastern Manchuria mentioned in ancient Chinese sources. The languages of Buyeo, Goguryeo, Dongye and Okjeo were said to be similar to one another but different from the languages of the Yilou and Mohe to the north (believed on non-linguistic grounds to be Tungusic).
