Examining the language in literary works is one of the important steps in realizing the science of literature. How is the language reflected in the new poetry and what steps have the modern poets taken to preserve the standard language? The fact is that the Persian language and literature get mixed up in the new poetry, and contrary to the abundance of this type of poetry, most of the poets, including these poets, have not done anything in the field of language, except to mix and confuse the elements of standard language and literary language. In Nusrat Rahmani's poetry, there are linguistic slips and errors, which show that unlike great poets, he did not have a deep and broad familiarity with language and its usage. In his poem, there are many errors related to the use of verbs, nouns, letters, adjectives and pronouns. In addition to that, Rahmani has made some mistakes in the use of documentary verbs, pluralization of nouns, incorrect precedence of adjectives, displacement in the use of letters, omission of letters in his poetry. Apparently, Rahmani's main goal in creating poetry was illustration; In fact, he has been a practical supporter of "Poetry for Image", however, in his illustrations, there are contradictions and contradictions, and for this reason, his poetry does not touch the heart as it should and does not affect the emotions of the audience. and this is the main reason why his poetry is no longer seen in the Persian poetry and literature.
