Semiotics emerged as a modern analytical methodology rooted in linguistic and structural foundations, seeking to transcend the superficial meaning of texts and deconstruct their deeper semantic systems. It does not stop at the apparent discourse but delves into its hidden layers to extract symbolic systems and contextual relationships that produce meaning and shape its concealed significations. The theory of Michael Riffaterre, the American scholar, is among the most significant theories in semiotics, playing a pivotal role in uncovering latent and hidden meanings in poetic texts.Within this framework, this research aims to analyze the poem "Sahifat al-Ahrar" by the poet Badr Shakir al-Sayyab using Michael Riffaterre’s semiotic approach, which relies on two readings: the heuristic (focusing on the textual surface level) and the retroactive (revealing hidden significations). In the heuristic reading, lexical and syntactic structures were analyzed, revealing al-Sayyab’s use of revolutionary terms such as "al-qayd" (shackles) and "al-nar" (fire), which reflect the conflict between oppression and liberation. Grammatical deviations were also identified, lending the text a strong expressive tone.In the retroactive reading, semantic accumulations such as "shackles and freedom" and "struggle and sacrifice" were discerned, emphasizing the inevitability of freedom’s triumph. Three descriptive systems were also derived: tyranny, struggle, and hope for a bright future. Additionally, the hypogram expressing the poem’s central message was extracted—that restraints cannot prevent revolution and that the people are the true force destined to prevail.The conclusion affirms that the poem carries an optimistic message of freedom’s victory and the demise of injustice, while highlighting the efficacy of Riffaterre’s approach in uncovering hidden meanings in poetic texts
