Repetition is considered a modern stylistic device, although it also appears in classical Arabic poetry. It constitutes a prominent feature in the structure of modern poetic texts, and no poetry collection is devoid of it. Its significance lies in both artistic and psychological aspects, enriching the semantic and rhythmic movement within a poetic text. In the modern era, repetition has become a fundamental element in contemporary prose poetry, affecting both the phonetic and semantic levels. It also allows critics to uncover hidden and elusive meanings. This study, employing a descriptive-analytical method, aims to explore the aesthetics of repetition in Yahya Al-Hammadi’s poetry. Understanding the nature of this technique and how it is constructed and artistically formulated reveals the poet’s success in making it an effective structural tool within his poetic text. The repetition and its aesthetic dimensions in Al-Hammadi’s work are divided into two sections, each comprising different patterns. The first section includes general repetition of sentences, letters, words, and similar elements. The second section focuses on the appearance of the same letters, sentences, and words in an organized form, known as geometric repetition. Here, repetition takes on a completely different character, serving as a stylistic device that simultaneously reveals the poet’s emotions and the events occupying the reader’s mind.
