This paper discusses the structure for coordination in Korean. Specifically, this paper takes the reductionist view on coordination that the structure for coordination should be reduced to the standard X'-schemata. Having examined the existing theories of coordination, this paper argues that a new approach to coordination with respect to Korean, and hopefully to natural language in general, is necessary. The main focus of this paper is on the so-called embedded coordination a la Y.-H. Kim (2003), which shows some hitherto unrevealed nature of coordination in Korean. Based on this kind of coordination, this paper proposes a novel theory of coordination.
