||Seo, Hong-Won. (2015). Coda Cluster Simplification in Korean. The Linguistic Association of Korea Journal 23(3), 17-29. The goal of this paper is to investigate some aspects of coda cluster simplification in Korean within the framework of Optimality Theory. Until now, although many studies have been conducted on coda cluster simplification in Korean, satisfactory answers were not given about an exception pattern. In the previous analyses, which consonant is retained or deleted in the output is determined based on whether a consonant is allowed in the coda or not. When dealing with dialectal variations, the interaction of two constraints, CodaSon and Align-R plays a crucial role in choosing the optimal form. However previous analyses have some drawback, in that they cannot explain the stem /ɨlph/ cite under their constraint ranking. Accordingly, we suggest the specifically decomposed constraints related to Max(place) and their ranking hierarchy, which have some advantages over the previous analyses. That is, the more specified the place of a consonant is, the less that consonant is deleted. In this vein, the most preferred target for the deletion is pharyngeals, and then they are followed by coronals.
