Goguryeo language

Speculated language of ancient Goguryeo

The Goguryeo language, or Koguryoan, was the language of the ancient kingdom of Goguryeo, one of the Three Kingdoms of Korea. Early Chinese histories state that the language was similar to those of Buyeo, Okjeo and Ye. Lee Ki-Moon grouped these four as the Puyŏ languages. The histories also stated that these languages were different from those of the Yilou and Mohe. All of these languages are unattested except for Goguryeo, for which evidence is limited and controversial.
