The research tagged with (Antonymy in Adonis's Arabic Poetry Collection) deals with the phenomenon of contradistinction in its two parts (singular and compound) in Adonis's collection of Arabic poetry by monitoring the positions of contradistinction in the divan and selecting models for analysis and study in order to reveal the stylistic shift caused by contradistinction in the phonetic and semantic levels of the poetic language.The research plan is based on an introduction, two parts, and a conclusion. As for the entrance, we clarified the concept of correspondence, ancient and modern. As for the first section, it bore the title (Singular Correspondence). (Complex opposition) We dealt with the poetic models in which the opposition of one structure to another was evident, and the conclusion finally included the most important findings of the research.The research relied on a variety of sources, including ancient and modern ones, and perhaps the most prominent sources that were employed: (Divan of Arabic Poetry) by Adonis as the main sample for the applied side of the research, as well as the book (Al-Taraz that includes the secrets of rhetoric and the sciences of the realities of miracles) by Yahya bin Hamzah Al-Alawi, and the research (The Phenomenon Correspondence in Semantics), by Dr. Ahmed Nassif Al-Janabi for the theoretical side of the research.The research aims to prove that opposition is a stylistic term that causes a shift in the poetic language at the phonetic and semantic levels, while the importance of the research comes from the collection chosen for the study as a poetic anthology that included Arabic poetry from the pre-Islamic era to the beginning of the twentieth century.
