Korean

The possibility of a genetic relation between Turkic and Korean, independently from Altaic, is suggested by some linguists. The linguist Kabak (2004) of the University of Würzburg states that Turkic and Korean share similar phonology as well as morphology. Li Yong-Sŏng (2014) suggest that there are several cognates between Turkic and Old Korean. He states that these supposed cognates can be useful to reconstruct the early Turkic language. According to him, words related to nature, earth and ruling but especially to the sky and stars seem to be cognates.

The linguist Choi suggested already in 1996 a close relationship between Turkic and Korean regardless of any Altaic connections:

In addition, the fact that the morphological elements are not easily borrowed between languages, added to the fact that the common morphological elements between Korean and Turkic are not less numerous than between Turkic and other Altaic languages, strengthens the possibility that there is a close genetic affinity between Korean and Turkic.

Many historians also point out a close non-linguistic relationship between Turkic peoples and Koreans. Especially close were the relations between the Göktürks and Goguryeo.
