Al-Wahidi is one of the greatest syntactic critics who have explained al-Mutanabbi's Anthology. His explanation contains concepts, and syntactic and critical opinions that deserve study and scrutiny. Al-Mutanabbi's poetry stands as a fertile domain for syntractic criticism as is apparent in the critical arena over his poetry. Through his syntactic judgement, al-Wahidi attempts to support a doctrine, oppose some point of view, elaborate on what violates a proposed principle, or uncover a certain problematic issue somewhere in al-Mutanabbi's poetry; specially when disagreement among critics' opinions appears, and dissimilarity among their doctrines and approaches materialises. Poetry was and is still one significant source to formulate the syntactic structure, even if it witnessed some unstability due to narrators' uncertainties, and imprecision of transference. So, narratives and narrators of poetry have varied, which has consequently created an obvious phenomenon that requires research, and study of the effect that may have on the syntactic rules. This is because syntax is one fundamental aspect of the culture of those interested in the literatry exegeses. This study comes to focus on one essential aspect of syntactic criticism that is already applied to al-Mutanabbi's poetry.
