In this paper I analyzed the facets of opening and closing structure of Folktale Discourse on the basis of discourse. In the framework of discourse structure I propose a whole story consists of upper structure and lower structure, which in turn can be divided into three parts, opening, telling and closing. The opening and closing part of the Folktale Discourse showed the unusual characteristics of oral literature, which is due to the distinctive traits of oral literature. An analysis of the Folktale has shown that basically folktale was composed of interaction between teller and audience and that``s why the way to open and close a tale has taken the similar form of interaction between teller and audience. The facet of opening part in the folktale has the following categories. (1)discourse mark (2)opening expression (3)question (4)telling source of information And the facets of closing part in the folktale is made up of the following structures. (1)indicating prior-information (2)telling source of prior-information (3)commenting (4)closing expression
