One way of expressing technique is to use metaphor in its general sense - to use one word or phrase instead of another based on the similarity between them. The use of metaphor as linguistic phenomena is not general in the literary language but specifically cognitive and mental occurrences, and what appears in language is merely a manifestation of this mental phenomenon. On the other hand, this cognitive and subjective expression of thoughts can be analyzed and interpreted in the context of critical discourse and linguistic criticism. The use of descriptive and intuitive metaphors in the poems of Nima Yushijj and Mehdi Akhavan Saleh can be one of the examples of critical discourse analysis approach from Fairclough's perspective. Accordingly, although the approach of critical discourse analysis prioritizes the relation of language, power, ideology, and discourse, the literature of nations
can also be analyzed and interpreted within the framework of critical discourse and linguistic criticism. In this descriptive-analytical research based on library studies, after studying the poems of these two poets, the descriptive and visual metaphors of the poems have been identified and quantitatively and qualitatively studied. Finally, by comparing the sonnets of Yushiij and Akhavan, it can be concluded that the metaphorical application of the prevailing political and social conditions and conditions in the Akhavan’s poems can be more conclusive. According to the above-mentioned intertextual analysis both poets have been influenced by the governing social and political conditions; however, this is more evident in the poetry of Akhavan.
