漢語의 遇攝과 流攝의 음운 변화와 한국 한자음에 반영된 시기 층위

Abstract

This study aims at reconstructing the phonological development of the Middle Chinese(MC) Yu(遇) and Liu(流) Rhyme Groups from Old Chinese(OC)to MC, and revealing their historical strata reflected on Sino-Korean. Although the two rhyme groups partly share the same OC origin, i.e., the Hou Group(侯部, *-o), the sound value of each rhyme group in MC is different from each other. It is significant to study the process of phonological changes of them,and is also significant to study why Sino-Korean reflections of each group,which are alleged to basically represent Mid Tang phonology, are identical in spite of the distinction between the two groups. The Mu Rhyme(模韻) in the Yu Rhyme Group originated from the OC Yu Group(魚部, *a), and developed into -o and is reconstructed as -wo in the Qieyun, later giving -u in the Huilin's Fanqie system. Sino-Korean '오' type reflects the a or early b layer. The Yu Rhme(虞韻) belonged to the OC Yu and Hou Groups in an early stage, and its phonological development is almost identical as that of the Mu Rhyme. Yu rhyme(虞韻) is reconstructed as -{j, ɯ}u in the Huilin, which Sino-Korean '우, 유' are believed to exactly reflect. The Yu Rhyme(魚韻) also originated from the OC Yu Group, but had belonged to the 'Kaikou(Open mouth)' until it merged with Yu Rhme in the late 10th Century. Sino-Korean '어' reflects the period before the two rhymes merged. Every Hou Rhyme(侯韻) character in the Liu Rhyme Group originated from the OC Hou Group but some of labial initials from the Zhi Group(之部). It is reconstructed as -u in the Qieyun, and was in the mid of changing to -ow in the Huilin. Therefore, Sino-Korean '우', most probably, may be placed in the a layer. The You and You Rhymes(尤, 幽韻) originated from the OC Yu Group(幽部, *-u) and had reserved their phonetic or phonological values as they had been in OC until they changed to -uw in the Huilin. Sino-Korean '우, 유' both seem to reflect the Huilin's b layer. Sino-Korean '우, 유' type appears in the both rhymes groups, which is attributed to the surface phonetic constraint of the Korean Syllables.
