韓･日･越漢字音での開口2等韻における受容様相の 比較考察

Abstract

The purpose of this study, we analyzed how the Grade Ⅱ rhymes of the used sounds are accommodated in the Chinese. The results are summarized as follows. 1) In Sino-Korean, the low-back vowel /ɑ/ of the first equal lyme was discriminated to「아」/a/ and the mid-back vowel /ʌ/ was discriminated to「ᆞ」/ɐ/. In addition, the low-front vowel /a/ of the bisexual rhyme was discriminated to「아」/a/ and the mid-front vowel /ɐ/ was discriminated to「」/ɐ/. In other words, in Sino-Korean, the difference between the front and back in mid-vowel is excluded and accepted as「아」/a/ and mid-back vowel “ʌ” as「」/ɐ/ with only the difference between low and middle. This means that “ɐ” as「」/ɐ/ existed as phonemes of Korean language from the acceptance stage of the rhymes, and the mid-back vowel ʌ and the mid-front vowel were accepted a「아」/ɐ/. It can be judged that the consonants form is the Qinyin(秦音). 2) In the acceptance process of Sino-Korean, there are three forms of substitution, joining, and declination due to differences in phonological structure between Chinese and Korean. The main factor is the difference in the number of vowels and one syllable. In the case of a single vowel, the vowel is replaced by another vowel in the Korean language with fewer vowels than the Chinese word. In the case of multiple vowels, Syllable. 3) The main vowel of the Grade Ⅰ and Grade Ⅱ was reflected as /a/ because Sino-Japanese Kan’on is the Qinyin(秦音) that all Grade Ⅰ and Grade Ⅱ are all joined. However, it can be seen that there is a strong tendency to substitute the lower prefrontal vowel /a/ with the mid-front vowel /ɐ/changes to /e/ and the mid-back vowel /ʌ/ changes to /o/. 4) Sino-Vietnamese are reflected in the main layer of Qinyin(秦音), which integrates both vowel of the Grade Ⅰ and Grade Ⅱ isochronous rhythm by reflecting both the low-back vowel /ɑ/ and the mid-back vowel /ʌ/ as /a/. However, it can be seen that that they are mixed of layers before Qinyin(秦音) because consonants /ə/ are also distinguished by「â 」/ə/ and「ǎ」/ǎ/.
