A Study on the Eogiseol in the Japanese Korean Language Education Society and Park Seung-bin(1931), the Theory of Conjugation of Korean Verbs and Adjectives

This paper compared the Park Seung-bin(1931) and the Eogiseol, which are currently used in the Korean language education society in Japan. For this purpose, we first investigated what is the Eogiseol and examined the formation process of it. In Eogiseol, Eogi is a combination of basic forms such as ‘먹’, ‘작’ and ‘-으-’ or ‘-아/어-’ which are thematic vowel, And three Eogie types are depending on the types of endings, and Eogies change their forms but endings are fixed. This shows the opposite perspective from the general conjugation theory that the stem does not change, but the ending changes. The formation process of Eogiseol generally shows the flow of ‘前間恭作→河野六郞→菅野裕臣→浜之上幸’, and it can be seen that the results obtained from the study of medieval Korean are applied to modern Korean. The similarities between the Eogiseol and Park Seung-bin(1931) are discussed in terms of similarities of phonetic realization of ‘먹으’+‘니’ of the Second-Eogi-type and ‘머그’+‘니’ of Park Seung-bin(1931), ‘먹어’+‘서’ of the Third-Eogi-type and ‘머거’+‘서’ of Park Seung-bin(1931), but if we look a little deeper, we can know that the way of spelling is different like ‘먹’ and ‘머그’, the basic type setting is different as ‘먹’ and ‘머그’, and the area of the stem is also different because it is up to ‘먹’ while ‘머’ is different. In addition, supporters of Eogisol argue advantages of the use of Eogisol in the Japanese Korean language education society in that Eogisol does not give learners much concern and can derive the conjugation type quickly and accurately in that it memorizes the form of Eogi according to the type of endings, but the theory of conjugation based on the premise that ‘-으-’ and ‘-아/어-’ belong to the stem can lead to a shift away from the essence of the conjugation of Korean verbs and adjectives that the stem does not change and the ending changes, so deeper consideration of the consistency of the theory is needed.
