18세기 譯書類 문헌과 王室 문헌의 音韻變化－ㄷ口蓋音化와 圓脣母音化를 중심으로－

Abstract

This study surveys the frequency of the phonological changes of non-palatal consonants into palatal ones before ‘i’ or ‘y’, and those of non-round vowels into round ones after labial stops in the middle and late eighteenth century. The examples were taken from translation works, Pag-tong-sa-sin-seok-eon-hae(朴通事新釋諺解, 1764) and Jung-gan- no-geol-dae-eon-hae(重刊老乞大諺解, 1795) and royal literatures, Eo-je(어졔, 1760s), Gyeong-se-mun-dab(경셰문답, 1760s) of King Yeongjo's reign and Yun-eum(倫音, 1780s~1790s) of King Jeongjo's reign. T-palatalization rate is 51.65% and 96.92% in the translation works, and 8.66% and 88.90% in the royal literature, respectively. The rate of the changes of non-round vowels into round ones was 23.73% and 5.73% in the translation works, and 1.19% and 15.07% in the royal literature, respectively. The rate remain more or less the same in the particular environments of pure-Korean(grammatical morphemes, morpheme boundaries, initial syllable in a lexical words, and non-initial syllable in a lexical words) and sino-Korean.The result shows that there are significant differences of the phonological changes between the translation works and the royal literature according to the social characteristics of each sources. It also shows that the diffusion processes of both phonological changes differ in differently categorized materials. Therefore it is necessary to conduct the research of Korean phonological changes under the socio-linguistic perspective, considering the social characteristics of the materials surveyed. And the research of the processes of the Korean phonological changes should be done in such a way that it can reveal both the universality and particularity of the language changes.
