According to the teachings of relevance theory, understanding the meaning of the speaker in metaphor is an inferential process that is defined based on the construction of a ad hoc concept of metaphor. This concept is created by semantic adjustments of the word according to the context and is considered as an explicit content of the text. The ad hoc concept has encyclopaedic information the of both sides of metaphor, but it may have emergent property that emerged during the interpretation. The emergence of emergent property in metaphor leads to the inference of weak implications that vary from audience to audience, but within the framework of the principle of optimal relevance and relevance-theoretic comprehension heuristic. This article has tried to examine the understanding of the meaning of the narrator in metaphor in a descriptive-analytical way, using examples from Qaisar Aminpour's poetry. The research results show that the presence of a ad hoc concept in Qaisar Aminpour's poetic metaphors has created a range of weak implications that have expanded the range of different interpretations of his poetry and based on the type of ideological attitudes and specific philosophical views. He is justifiable to the world. This has made the readers more interested in the poetry of Qaisar Aminpour and made it more influential.
