According to H. Paul Grice's intention--based semantics, the sentences are requiredto have been structured within rational principles in order to assume the conversationor communication stimulating. By classifying the conversation among theindividuals into two such as the "natural meaning" and the "non-natural meaning",Grice, indeed, identifies that every sentence uttered by an utterer is functional incommunicative context. Accordingly, individuals' understanding one another pro--foundly depends upon the things that they want to say rather than the things that they say. Thus, Grice proposed the general principles under the title of "cooperativeprinciple and the maxims of conversation", norm governing all coop--erative interactions among humans such as: "Maxim of quantity", where the utterer'scontribution is as informative as is required; "maxim of quality", where theutterer attempts at making his/her contribution one that is true; "maxim of relation",where the utterer's contribution focuses on relevance to the conversation;and lastly, "maxim of manner", where the utterer contributes by avoiding obscureexpressions. In this study, the Story of Wild Dumrul Son of Dukha Koja in TheBook of Dede Korkut, one of the most ancient epic stories of the Oghuz Turksand narration which presents semantic data on the communicative cultural aspectsof the Oghuz, will be analysed through Grice's intention--based semantics byconsidering "cooperative principle and the maxims of conversation". The result ofthe study reveals that to what extend the utterers will be loyal to the cooperativeprinciples such as maxim of quantity, quality, relation and manner and the studywill also uncover the communicative characteristics of the Oghuz Turks.
