عنوان مقاله [English]
The grammatical metaphor means the replacement of a grammatical class or a grammatical structure with another class or structure. This metaphor can be seen more in the ideational and interpersonal meta-function. On the one hand, the ideational processes, their changes, and their naming are contributing to the development of grammatical metaphor. On the other hand, when this metaphor enters into the social and interpersonal meta-function of the language, speakers use grammatical structures to perform unusual tasks. Therefore, the grammatical metaphor in each of these meta-functions can change the actors and meanings of the processes. However, some believe that this metaphor is specific to scientific texts that are more objectified. The use of this metaphor in other texts can also be useful in analyzing various aspects of the text.Historical texts including texts that claim to report reality, when seen from this perspective, are close to scientific texts. Among these texts is Beyhaghi’s history, in which the author repeatedly emphasized the statement of reality. It seems that grammatical metaphor can be effective in assessing the validity of this work. In this study, to investigate Beyhagi's claim, we examined the story of Hassanak-e- Vazir in terms of grammatical metaphor. The results of the research show that material processes are the most important components of this text. Also the declarative mood that represents the actual report is dominant in this work, but beside that the subjunctive mood, which is the opposite of the declarative mood, is seen in many processes, such as nominal grammatical metaphors, alternative meanings, the use of sentences in unusual roles, the application of processes to each other in interpersonal meta-function, the elimination of the agent or the process actor, and some additional results of this research. The use of the active verb in the sense of the passive in order to remove the process actor can be considered a new type of grammatical metaphor most frequently used in this section. Based on the findings, we can say that Beyhaghi, while emphasizing the facts, does not report the reality completely. He tells a part of the fact that is safe or low risk, but he also eliminates some parts or does not explicitly state them, especially in the constructions concerning how Massoud Ghaznavi is a true actor in the process, using various forms of grammatical metaphor to keep his name.
