For the folklorists and linguists who are serious students of what has been designated a minor genre the riddle is in fact a complex linguistic and aesthetic structure that when subjected to systematic and scientific study reveals a great deal about the major human systemssuch as language culture and artwith which it is inextricably bound up. Riddles conform to a model of communication made up of a code and an encoded message that is first transmitted and then decoded. As what Professors Pepicello and Green term a licensed artful communication the riddle employs quite ordinary language in conventional ways to satisfy the demands placed upon it as the art form that it is. And as an art form the riddle is subject to constraints that are semiotic some primary graphic aural or other code aesthetic artistic conventions that are also semiotic and grammatical linguistic restrictions. The riddle operates therefore within a cultural framework that is entirely predetermined and represents what Pepicello and Green designate a conventional performance. The signified of riddles is not easily defined and indeed it is possibleperhaps even necessaryto distinguish several signata. All riddles the authors point out whether they are based on grammatical or metaphorical ambiguity or represent one of the transitional types they identify are solvable within the confines of the culture in which they have been constructed and in which they are posed. But the signified of a riddle is not its answer. Nor is it an object or a situation. Rather it is the code employed by the riddle itself. Riddles are therefore metalinguistic ways of using language to deal with languageways of using language to gain mastery over language. W. J.
