This research work is a complex study of the phenomenon of polycodity in modern English-language poetic works. In the theoretical part of the work, such fundamental concepts as "discourse", "polycodity", "intermediality" and other terms that are necessary for a deeper understanding of the topic and subsequent analysis of works were considered. We also paid special attention to the following controversial points concerning the terminology and the theory of polycodity: the differences between the terms "polycode" and "creolized text", the researchers’ controversy regarding the classification of creolized texts and the identification of intermediate typologies. The practical part of the study was based on the poetry collections of modern English-language poets who combined different ways of implementing polycodity in their works. Tom Phillips' collection "A Humument" was analyzed as an example of visual poetry; "Milk and Honey" by Rupi Kaur was chosen for the study of poetry with author's illustrations, and the phenomenon of ekphrasis was studied based on the poetry collection "Three Men on the Metro" by A. Croft, W. Herbert and P. Summers. As a result of using the combination of methods of intermediate and linguistic analysis of the text, we were able to study the mechanisms of the implementation of polycodity in poetic texts, the reasons and ways of expanding the semantic space of such works and the features of their impact on the reader's consciousness.
