A riddle takes on a pathway of communication which is completely opposite to the conventional communication methods. Communication through a riddle is rather \"a process of turning the communication itself into a message\" than \"a process of communicating a message\". This unconventional communication mechanism of riddle requires manipulation of language. Miscommunication arising from using a riddle as a communication tool, is mainly due to the fact that a riddle turns communication itself into a message, that is, the delivery process itself becomes a message. This thesis aims to identify various problems that occur as this particular characteristic of a riddle becomes incorporated into a story. In order to discuss riddle-tales, the fundamental poetics of riddle needs to be reviewed first. It is necessary to analyze the influence that the poetics of riddles has on how riddle-tales are structured and developed. Against this backdrop, this thesis examines the relations between riddles and riddle-tales in three parts. Specifically, in the first part, the intriguing and entertaining attribute of riddles will be examined. The second part will look at the manipulative element of riddles and productivity of riddle-tales. Finally, how the information monopoly of riddles and informative attribute of riddle-tales are related, will be analyzed. riddle-tales with intriguing elements of riddles reflect the characteristics of riddles as folk play. In this case, the intriguing elements of riddles define the nature of a story. On the other hand, manipulative elements of riddles are concerned with the provability and productivity of a story, rather than defining the nature of a story. Delay in communication caused by riddles will eventually contribute to making the story more likely and interesting. Manipulative attribute of riddles increases the informative aspect of a riddle tale, thereby causing the audience to become absorbed in the story. In addition, the information monopoly, that refers to the exclusive possession of information by a story teller, gives the teller the ability to balance between the informativeness and predictability, instead of leading to excessive informativeness and thus seriously damaging the predictability of a riddle tale. Performing riddle-tales is a representative genre which combines games and stories. This study is not intended to discuss different ways the subsystems within a larger system of folk arts are consolidated or conflict with one another. Sub-genre of fold arts such as performing riddle-tales is discussed in a way that explains how different genres of folk arts interact with one another. And this presents a challenging subject for further debate in that it can help identify the specific genre of individual fold arts and emphasize the dynamics among different genre of folk arts.
