comparison of appellations in the ''History of Sistan'' & “Poems of Khaghani”

One of the most interesting questions for humans is the reason for naming things (the appellation). In the texts of Persian poetry and prose, some writers and poets, in the course of their works, Etymologized some words and define their appellation(the reason of naming). Studying, analyzing, and classifying these appellations, indicates the way they look at the construction of words. In this article, some of these appellations that are included in the ''history of Sistan'' and "Divan-e-Khaghani" are examined and compared. For this purpose, we categorized the types of the appellation and mentioned the evidence from different books. Then we extracted and examined the examples of the appellation from the ''history of Sistan'' and "Divan-e-Khaghani". By examining the samples, it was found that the author of the ''history of Sistan'' has paid more attention to the etymology of words in expressing the appellation, and in some cases, he has referred to the Folklore but Khaghani has paid more attention to poetic games with words and offers innovative appellation. Of course, he has also paid attention to the appellation mentioned in other books. This article has been written in a descriptive-analytical way and the data has been collected in the library method. Although several articles have been published on the subject of the ''Appellation'' but so far no independent article has been published on the subject of ''Appellation in the history of Sistan''.
