산포이론에 의한 제주방언의 음운적 특성 분석

Abstract

This paper provides a new account on the characteristic of Jeju dialect phonology. For this purpose, we employ the frameworks of Optimality Theory(McCarthy & Prince 1995) and Dispersion Theory(Flemming 1995). The vowel system of Jeju dialect is undergoing rapid change. It was caused by structural factors, disappearing of opposition, merging or shift of phonemes. In Jeju dialect, each change of vowel system has a certain direction based on some factors. However, the point of change are definitely different in age. Though the process of change is somewhat different in each age, Jeju dialect has changed to an asymmetrical 7 vowel system from a symmetrical 9 vowel system. On the other hand, the palatalization of Jeju dialect has changed to /t/ palatalization from /t/, /k/, /h/ palatalization. Also, the point of change are definitely different in age. But for the change of palatalization, articulation place of consonants increase to bilabial, palatal, velar, glottal. Therefore, I will argue that the final output of vowel and consonant system is a consequence of constraint interactions. Here I propose a pattern evaluation procedure for explaining the consequence of vowel and consonant system change. Finally, I show that the change of vowel and consonant system can be better described by dividing it into three and two stages and that each stage requires a different constraint ranking accounting for its change more precisely.
