The Korean Language circles presented two standpoints about the formation of Goryeo language.
First, the Goryeo language was based on the Silla language. In other words, the Korean languages were divided into Buyeo languag (Northern languages that Goguryeo language represented Han and Buyeo languages as one of Altaic languages) and Han languages(Southern
languages represented by Silla language) for about 600 to 700 years. As Silla unified three kingdoms, Goguryeo, Baekje and Silla in mid-7th century, all languages were unified around Silla language around the end of 7th century. Since then, Goryeo inherited the Unified Silla and
Goryeo language was naturally formed on the basis of Silla language.
Second, Goryeo language was formed on the basis of Goguryeo language. That is, Goryeo language was formed around Gaegyeong language( Gaeseong language). And Gaegyeong (Gaeseong) originally belonged to Goguryeo. Thus, Gaegyeong language( Gaeseong language)
has to be considered not as one of Silla dialects but as one of Goguryeo dialects. Thus, Goryeo language based on Gaegyeong language( Gaeseong language) is one of Goguryeo dialects.
Two standpoints above can't basically compromised. The differences of two standpoints are summarized below.
First, the first standpoint considered Goguryeo language, Baekje language and Silla language as the heterogeneous languages with the different lines while the second standpoint considered those languages in the same line just with the difference in dialects.
Second, while the first standpoint insisted that the unified main language in the Korean language was formed at the end of 7th century when the Unified Silla had been constituted, the second standpoint explained the unified main language was formed in the early 10th century when Goryeo had been established.
Third, the first standpoint argued that Goryeo language was formed as Goguryeo language(1ow class language) was substituted by Silla language(high class language). However, the second standpoint pointed out that the languages in the same line couldn't be completely substituted each other without any traces so that the formation of Goryeo language couldn't be explained by the substitution of language.
This study aims to identify which standpoints above were feasible in the scientific aspect. In other words, the purpose of this study is to discuss whether Goryeo language was formed as Silla language substituted Goguryeo language.
Meanwhile, two standpoints above, that is, the standpoints of Korean language circles on the formation of Goryeo language, mainly focused on identifying the similarity or the heterogeneity among Goguryeo language, Baekje language and Silla language. Thus, two standpoints faced the limit in the aspect that they weren't stated with the focus on identifying the similarity or the heterogeneity among Goguryeo language, Baekje language and Silla language after directly clarifying vocabularies. phonology and grammar of Goryeo language.
In consequence, this study identifies whether Goguryeo language and Goryeo language were homogeneous or heterogeneous in the aspects of vocabularies, phonology and grammar.
According to the research, this study clarified that Goryeo language was not formed by Silla language substituting Goguryeo language but by naturally inheriting Goguryeo language. The basis was the similarity of vocabularies, phonology and grammar between Goguryeo language
and Goryeo language.
