Evidence of 100 Khorasani dialect words in the poems of 30 ancient Persian poets

The purpose of this article is to examine 100 Khorasani dialect words in the poems of 30 ancient Persian poets to show that their use is still current in the dialect of the people of eastern Iran and western Afghanistan, but it has not been searchable in standard Persian. Being aware of these words in Khorasani dialects solves the issue of understanding some ancient Persian poems. Farsi language in large parts of the central and southern regions of Khorasan due to its distance from the center or being located next to the Lut desert, has less mixed with other languages and has generally preserved its original Persian words. On the other hand, there are various dialects of Persian language in the territory of Afghanistan, among which we can mention Herati, Kabuli, Tajik and Hazargi. Despite the separation of the western regions of Afghanistan from the land of Khorasan about a century and a half ago, many linguistic and dialectal similarities are evident in the words of the people on both sides of the border. There is no dialect map in which the borders of the Farsi dialects of eastern Iran and western Afghanistan are marked. Therefore, for this lexical review, the researcher has considered the common Persian dialects in Afghanistan, and in this regard, he has benefited from the dialectical knowledge of Afghan students living in Birjand University. The researcher searched for the required words in the lexical corpus collected in a field research titled comparative study of the dialects of the eastern border of Iran. In this research, he has entered 100 selected words along with their meaning and related examples as well as their current usage in the cities of Khorasan in Persian alphabetical order.
