In this paper discourse is considered as a semiotical concept, introduced by the structuralists. In the "explanatory dictionary of language theory" by A.J. Freimas and J. Cantet where discours is interprited as a semiotical process, which is realized in various types of discourse practice. In narratologie a distinction is made between discourse levels, where narrative instances act in written form in the text of works: explicit author, explicit reader, "characters" etc and between abstract – communicative level, where implicit author, implicit reader narrator act in impersonal narration. In some of the research works of the structuralists and post poststructuralists, the notion of the texts gets wide concept of interpretation and the conscience of a man is identified with the written text: history literature and society. As a result the culture was percepted as a common intertext serving as a pretext to any reappearing new text. Christeva states that the concept of intertextuality reminds us that each text exists in rebation to others. The paper shares Genett's idea of proposing the use of so-called narrow concept of intertext regarding it as interaction of different types of discourse, where the narrative instances represent the members of a communications chain: real author, and a reader on an intratextual level along with numerous intertextual instances.
