음운과정의 불투명성과 어휘부의 최적화: ‘ㄹ-불규칙용언’의 분석을 중심으로

Lee, Sechang. 2004. Opacity of Phonological Process and Lexicon Optimization. Korean Journal of Linguistics, 29-1, 85-105. The purpose of this paper is to account for some of the opaque phonological behaviors of the so-called ‘/l/-irregular stems’ of Korean. I deduce a new optimization principle of lexicon from Prince & Smolensky's one, by which I claim that language learners are supposed to posit some prominent prosodic information in the input forms in the course of their learning. I assume that the relevant prosodic information is abstracted away from output forms and instrumental in postulating the proper input forms. Various irregular alternations will be analyzed and proven to be regular in the sense of the new principle of lexicon optimization. (Sookmyung Women’s University)
