The purpose of this thesis is to suggest a more effective and consistent analysis of English stress, which has been a major concern in the studies of phonology. In order to achieve this goal, this study surveys previous analyses of English stress and shows that optimality theory is a better method than the previous ones in analyzing English stress phenomenon. Chpater I presents the purpose and the scope of this study. Chapter II and III review the theoretical bacdground of the reserch, focusing on two major previous studise: a lineaf approach called SPE, which is developed by Chomsky and Halle(1968), and a non-linear approach called Metrical Phonology, which is propoded by Liberman and Prince(1977). In SPE, stress is regarded as n-ary reature and it needs a lot of stress rules to explain various English stress types, adding the complexity to those rules. In Metrical Phonolgy, on the other hand, these problems are easily settled because stress is considered a binary-feature manifested by relative prominence among syllables. The theroy assumes that the stress assignment should be based on the hidrarchical metrical tree structure, or metircal grid, representing relative prominenct of the word. Chapter IV and V describe the basic concepts of Optimality Theory, a constraint framework, and its theoretical implications, based on serveral examples found in English stress phenomenon and I point out that Optimality is a better approach than the previous ones in explaining thestress assignment on English words. In addition, I discuss some important concepts in the Optimality Theory which include Ranking, Directional Effedts, ALIGN-HD, Cyclicity, Extrametricality Optimality theory.
