Objective. The main objective of this research is to analyse the cognitive and communicative-pragmatic parameters of intertextuality in modern mediatexts. The article deals with the peculiarities of intertextuality expression in mass media as well as identifies the main varieties of intertexts and considers their role in newspaper articles of the information-analytical weekly “Dzerkalo tyzhnya”. Research methods. Discourse analysis technique helped to identify textual and extratextual characteristics of media content. At various stages of the study, a functional analysis method is used to determine intertextuality as a means of receiving text-formation. Communicative-pragmatic analysis allowed us to find out the conditions of formation of intertextuality and generation of new meanings in intertextual crossings, which is oriented on the cognitive-speech interaction of the participants of communication (author-reader). The psycholinguistic method has become the main scientific way of studying the processes of origin and perception of intertextuality in mediatexts. The common scientific methods of analysis and synthesis, induction and deduction, systematization, special scientific techniques of linguistic text analysis have also been used. Results. The mediatext is a dynamic linguistic phenomenon, which responds promptly and responsibly to social-political, social-cultural and linguistic changes, reflecting the present realities in various ways. In the process of text-forming journalists try to expand the arsenal of professional means with a variety and original innovations, one of them is intertextuality. The main intertextuality means in mediatexts are quotations, allusions and reminiscences, which are good migration ways of familiar stories, events, people, expressions in the context of mass media. These elements are integrated into the new text, cause new emotions and associations, which revive cognitive interest to the material. Conclusions. Intertextuality is defined as a cognitive and communicative-pragmatic category, which realizes in modern mediatexts, activates cognitive and thoughtful activity of the author-journalist and the reader, stimulates intellectual searches of both communicants in the broad social-cultural space of many generations of humanity. The psycholinguistic mechanisms of the intertexts use in mass media are related to the actualization of certain images in the journalist’s mind and their verbal presentation with well-known expressions, symbols, stories.
