제약서열의 통시적 변경에 따른 공시적 음운과정의 불규칙성에 관한 연구: 'ㅅ-불규칙용언'의 역사적 변천을 중심으로

초록

This article aims to explain the synchronically opaque phonological behaviors of the so-called ‘/s/-irregular stems’ of Korean. I claim that it is not hard to see that synchronic phonological systems do operate elegantly, once the historical perspective is adopted. I review the actual historical sound changes the relevant sounds underwent in terms of constraint re-ranking. Specifically, I argue that the re-ranking of relevant constraints was totally responsible for the loss of a particular phoneme, which in turn produced the opacity in current phonological system of Korean. It will also be demonstrated that the admittedly unpredictable alternation of stem-final /s/ of the contemporary Korean could be analyzed synchronically successfully with a single ranking of constraints I propose in this article.
