Comparative Study of Dari Arabic and Farsi Language Sources

In this research, a descriptive-analytical method has been used. Our main goal in the present research was to compare the sources in Dari Arabic and Farsi language. The findings of this research indicate that sources in Arabic and Dari Persian have similarities and differences, each of which is specific to itself, but sources in Arabic form the principle of derivation, with the description of this There is also a difference between literary schools in this field, but in Persian language it can be used as a verb, subject, object, noun and adjective in a sentence. So, some differences in their divisions can also be seen. The infinitive in Dari Arabic and Farsi languages plays an important role in the formation and arrangement of sentences, and by using these infinitives, different concepts and actions can be expressed in these languages. The main question that has been addressed is how sources in Dari Arabic and Farsi are defined and with what considerations, what are the similarities and differences of sources and their types in Arabic and Persian. New approaches about the sources of Persian language are proposed and analyzed as an independent grammatical unit These approaches show the improvement and development of the concept of infinitive in Persian grammar and indicate the acceptance and use of infinitive as a dynamic and multiple grammatical unit. These approaches can contribute to the diversity and richness of the meanings and structures of the Persian language and increase the ability to express different concepts in this language.
