The goal of this paper is to reanalyze the structure of 'eumcikha(음직하)' in Korean. We have several important previous works for it. This paper argued against previous works and pointed outd their problems. At first, this paper regarded the construction of 'eumcikha' as one of the modality dependent noun constructions. In this paper I proposed some possibilities of new structure of 'eumcikha'. 1) The structure of 'eumcikha' is not regarded as the 'embedded sentence+upper sentence' construction. 2) It is not also considered as the 'main verb+auxiliary verb' construction. 3) It is not recognized as a morphological one unit, although they have lots of in common. In this paper, I proposed that the construction of 'eumcikha' has both syntactic property and morphological property. Owing to these properties, it is so difficult to determine the structure of it.
