The purpose of this paper is to investigate the semantic combination of ‘self+N’ in Korean. It is assumed that the basic meaning of ‘self’ is reflexive. The reflexivity is defined as follows; ⅰ) a property that a relation between Agent(X) and Theme / Experiencer / Recipient(X) is coreferent. ⅱ) a property that action of X turns back to oneself. ① ‘self’ is filled as a REF in the argument slot of Theme/Experiencer/Recipient on Descriptive Tier. ② Agent and REF are coreferent on Referential Tier. Through ① and ②, the semantic combination of ‘self+N’ is explicated satisfactorily. It is possible to divide ‘self+N’ into four groups, such as ‘self suyu’, ‘self secha’, ‘self coffee’, ‘self camera’. Every ‘self+N’ construction is related to a commercial event except ‘self suyu’ and ‘self camera’. I explain the semantic combination of ‘self secha’/‘self coffee’ with importing meaning of service. And I explain the semantic combination of ‘self camera’ with extracting event structure from agentive and telic of qualia structure of ‘camera’.
