한국어 음운규칙 적용의 한계와 그 대체 기제

Abstract

In Korean phonology, once the stem final consonant deletion rule is applied, no other obligatory rules can be applied. For example, when verb stem /hulth-/ hackle is combined with interrogative ending /-ni/ is it?, consonant cluster simplification rule must be applied and consequently /hul ni/ is derived. After this application, the l deletion rule, which is obligatorily applied in front of initial n, never be applied. Firstly, I define this case as the limit of rule application. In substitute for l deletion rule, the lateralization rule is applied, and so the derived realization comes as [ u i](←/hulli/). Secondly, I define this case as the alternative mechanism for the limit of rule application. The limit of rule application occurs when rule application affects the lexical meaning of stem or the grammatical meaning of ending if applied, and then the alternative mechanisms works as not applying any rules or applying rules unexpected. This alternative mechanisms help the listener to recognize the difference between underlying representation and surface representation, and to assume the real underlying representation without changing any meaning of stems and endings.
