[153] [154], Based on this text, Lee Ki-Moon divided the languages spoken on the Korean peninsula at that time into Puyŏ and Han groups. Early Chinese histories state that it was similar to the languages of Buyeo, Okjeo and Ye, all of which are unattested. [186] The Japanese history Nihon Shoki , compiled in the early 8th century from earlier documents, including some from Baekje, records 42 Baekje words. Samhan, or Three Han, is the collective name of the Byeonhan, Jinhan, and Mahan confederacies that emerged in the first century BC during the Proto–Three Kingdoms of Korea, or Samhan, period. [117] Similarly, Koreanic *r is said to result from the merger of four proto-Altaic liquids. 2015 found East Asian admixture in Andamanese which may represent the introduction of D clade. As there is disagreement among experts when the expansion of Koreanic languages started, there is room for interpretation on the proto-historical and historical extent of the Japonic language presence in the central and southern Korean peninsula. [9] Earlier forms, written with Chinese characters using a variety of strategies, are much more obscure. A monograph by Christopher Beckwith (2004) has established about 140 lexical items in the Goguryeo corpus. [21] [22] Korean labourers were forcibly moved to Manchuria as part of the Japanese occupation of Manchuria. (2011) "Automated Dating of the World’s Language Families Based on Lexical Similarity. (These languages are very poorly attested and their affiliation is uncertain. "...[T]his selection of features does not provide good evidence for common descent....we can observe convergence rather than divergence between Turkic and Mongolic languages--a pattern than is easily explainable by borrowing and diffusion rather than common descent," Asya Pereltsvaig, Languages of the World, An Introduction (2012, Cambridge). [123] The phoneme inventories of the two proto-languages are similar, with a single series of obstruents, a single liquid consonant and six or seven vowels. [49][50], The Japanese linguist Tatsumine Katayama (2004) found many similar basic words between Ainu and Japanese.

Vovin, Alexander. found that modern Koreans formed from a southern Chinese/Southeast Asian component and a Siberian component, which are both also closely related to each other. According to several historians and linguists, such as Ahn, Lee, Whitman, Janhunen, Vovin, Unger, Bellwood, and Hasegawa, Japonic languages were spoken in parts of the Korean Peninsula before they were replaced by Koreanic speakers. Many topographic names can be linked to Japonic but not Korean. He refers his theory to the “dual-structure model” of Japanese origin between Jōmon and Yayoi.
