ㅅ(>ㅿ)의 유지와 탈락

The -s->-z- intersonorant voicing

This is a study of Jeollanamdo dialect about a sound '/z/(ㅿ)' which is from the historical literature. This research aims to prove '/z/(ㅿ)' was allophone of '/s/(ㅅ)' and to be concreted its intersonorant voicing conditions of morphology and phonology. Follows are conclusions; (1) In the Middle age Korean, a sound '/z/(ㅿ)' was an allophone of '/s/(ㅅ)' by intersonorant voicing sound of '/s/(ㅅ)'. In historical literature, '/z/(ㅿ)'&'/s/ (ㅅ)', they were not a minimal pair. Moreover it matched with Jeonnam dialect '/s/(ㅅ)' which is original form '/s/(ㅅ)'. The other hand, sino-Korean '/z/(ㅿ)' was a single consonant. It was a word-initial '/s/, /z/' and it had their own meaning. (2) '/s/>/z/ as original 'Korean had showed often between high-sonority vowels. In Mid-age Korean, high-sonority vowels were '/ㆍ/, /ㅡ/' ; unrounded back vowels-mid, high vowels. Therefor '/s/>/z/' intersonorant voicing happened with '/ㆍ/, /ㅡ/'. Especially it applied this condition, that is between high sonority vowels like '/ㆍ～ㆍ/, /ㅡ～ㅡ/' over another conditions. (3) /s/>/z/' as original Korean, applied on inside of morpheme at first. And then applied on boundary of a complex word, an inflected word, an uninflected word. It means '/s/>/z/' application showed up more frequently with closed morphemes.
