An Analysis on the Origin of Chinese Words Clearly Identified in ShuoWenJieZi and YuPian that Originated from Joseon Region: Focusing on the Comparison with the Explanation in FangYan of the Han Dynasty

Seven Chinese words clearly recorded as originating from the historical regions of Gojoseon kingdom Known as the first nation of the Korean people, such as Joseon, Joseon-Ryeolsu, Northern Yan, and Northern suburb of Yan, were registered in ShuoWenJieZi and Yupian which have been evaluated as authoritative language materials in the history of Chinese linguistics. On the other hand, FangYan, the oldest dialect dictionary compiled in the early 1st century A.D., prior to ShuoWenJieZi and Yupian, also contains the above seven Chinese words, all of which are described as words used in areas related to Gojoseon kingdom.Comparing the explanations of the above three language materials for these seven Chinese characters, it can be fully assumed that all cases were deeply influenced by FangYan, even if there are no citation marks in some cases, because the explanations of ShuoWenJieZi and Yupian are the same or very similar to those of FangYan. However, no evidence has been found that these seven cases of Chinese characters originated from Old Chinese in the use cases of Chinese literature prior to FangYan.Therefore, it is highly likely that these seven Chinese characters, which were recorded in ShuoWenJieZi and Yupian following FangYan, originated in language of Gojoseon area that was not Old Chinese but probably proto-Korean language. Considering the academic status and value of these three language materials, it could be said that there is no reason to deny the origin of the Chinese characters specified in the language materials unless there is a clear anti-argument or active evidence of opposition.
