Review and analysis of different grammatical opinions about an important grammatical point (pronoun identification)

The subject of this research is the study of the role of dependents after the pronouns of the speaker and the addressee (us and you) in Persian. This issue is known in Arabic for its specificity and is called such special dependencies, which is one of the exact appointments, but in Persian, there is no specific name for such dependencies. A group of grammarians have not dealt with this at all; Some have called them a substitute (and inflection of expression) and Khayyampour has called such a dependent a messenger. Given the role of grammatical rules in language teaching and also due to the divergence of opinions in this regard, it seems necessary to address this issue. For this purpose, more than fifteen grammar books have been selected as a sample from the statistical community - which is a book of published books and articles - and in them, the categories related to this issue (exchange and conversion) have been studied. The research is of library type and descriptive-analytical method. The result shows that calling such an exchange or inflection an expression or a metaphor is not such a precise and scientific dependence. Studying this article gives a better understanding of this category.
