Cohesion is an essential notion within textual linguistics as cohesion has alwaysbeen at the heart of the research studies that focus on textual analysis, because cohesion places a great impact not just on the different components of a text but on the entire text as a complete and overlapping system. Thus, this study aims to highlight the textual cohesion and its impact on the organisation of sentences and paragraphs within the textual system. The study also deals with the factors and mechanisms that are linked to the parts of the text at the grammatical, lexical and pragmatic levels which together allow the writer to express a thorough and explicit meaning and to consequently form a text that enjoys and contains all the textual characteristics.The study shows that despite the uniqueness that characterizes the linguistics of the text that Western linguists consider as a separate branch, the roots of this have been present within the Arabic linguistic heritage, but have been dealt with as distinct parts, especially within areas such as grammar and rhetoric.The present work has chosen the poetry of ʿAbd Al-Wahhāb Al-Bayyātī as the subject of this study. Together with his contemporaries, this pioneer poet has contributed to the revival of modern Arabic poetry towards the end of the first half of the twentieth century he presented bountiful poetic productions with an innovative style that suit the ongoing developments of his time. The study focuses on the presence of textual concepts in Al-Bayyātī’s poems, and his ability to use and exploit these notions on the one hand and to achieve the element of textuality in his poems on the other hand. This reveals his deep, rich, profound and diverse poetic experience that merged heritage and modernity.
