The possibility of a genetic relation between Turkic and Koreanic, independently from Altaic, is suggested by some linguists.[1][2][3] The linguist Kabak (2004) of the University of Würzburg states that Turkic and Korean share similar phonology as well as morphology.[citation needed] 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.[2]
