Lee, Young-Hem. 1998. Semantic Ambiguities of the Internal and Eternal Arguments in Korean Verbs. Linguistics, 6-1, 45-6t The purpose of this paper is to explore the semantic ambiguities of the internal and external argument structures in Korean verbs. Traditionally the serial verbs were not distinguished from the the compound verbs in Korean, therefore there wasn`t any discussion about the argument structures. However, we will regard the predicate which includes the internal arguments as a constituents of the predicate semantically. The multiple subject construction was regarded as a propositional expression syntactically. We aslo provide a device on how to formalized the internal arguments and the predicates as a semantic unit. For instance, KKoch-ga pi-ta(bloom) was not regarded as propositional expression but a simple predicate in this paper. The expressions meokko-nol-ta (eat and play/ live an idle life) and meokko-po-ta (has eaten) could be treated as the serial verbs. But the argument structures of the verbs are quite different The verb meokko-nol-ta itself does not have any ambiguity, but the verb could be interpreted as an ambiguous expression depending on the structures. In section 1, we try to distinguish the compound verbs and serial verbs. And in section 2, we point out the difference of internal and external arguments. In section 3, we analyse the argument structures for the transitive and intransitive verbs. In section 4, we give a formalization for the combination of the second subject and the predicates. Finally we summarize the predicate structure of multiple subject constructions. (Chosun University)
