中子音에 의한 位置 同化에 대하여 －咸北 方言의 /ㅇ/→/ㄴ/ 현상을 중심으로－

Abstract

The purpose of this paper is to clarify the mechanism of the place assimilation by central consonants focusing on the /ŋ/→/n/ phenomenon of the Hambuk dialect. The main points of my discussion are as below. First, there exists ‘/ŋ/-centralization', a phenomenon that a peripheral consonant /ŋ/ which is adjacent to central consonants optionally changes into a central consonant /n/ in the Hambuk dialect. Besides, there exists ‘/m/- centralization', a phenomenon that /m/ optionally changes into /n/ as well. These phenomena belong to the place assimilation of which the assim- ilators are central consonants. Second, /ŋ/→/n/ phenomenon and /m/→/n/ phenomenon occur in front of palatal sounds as well as in front of alveolar sounds. This means that alveolar sounds and palatal sounds form the natural class of central consonants and they show the same phono- logical behavior. Third, the centralization of consonants is implemented in three ways: regressive assimilation by adjacent consonants, progressive assimi- lation by remote consonants and bidirectional assimilation of which assimilators precede and follow the assimilated sounds. In the case of bidi- rectional assimilation, the assimilating power on the assimilated sounds is even stronger than in the case of unidirectional assimilation.
