15-18세기 일본어의 청음과 탁음의음운론적 대립에 관해서

Abstract

The aim of this study is to clarify the process of the sound changes of Japanese consonants in the analysis of the transcriptions of Korean Source-Materials (i.e. Japanese textbooks for Korean and the records of travel in Japan) written in the 15-18th centuries, which are written with the Korean writing system. The results are as follows. 1) In the 15th century, all Dakuons(濁音) /g d z b/ had nasality. 2) The nasality of /z/ and /b/ ザ行·バ行　disappeared in the 16th century. 3) The nasality of /d/ ダ行　disappeared in the late 17th century. 4) In the 15-18th centuries, the phonetic property of Seion(淸音) /k t s/ was different from that of the present Tokyo dialect. 5) In the 15th century, the opposition of seidaku(淸濁) was basically that of nasality. 6) The opposition of seidaku(淸濁) changed to that of voicedness from that of nasality.
