The subject of this book is the similarities in the definitions, terms, and rules in the Indian and Arabic languages, which is arranged in three parts: the historical background of the development of Arabic grammar and the contribution of Iranian scientists to it, the arrangement of Indian letters and its divisions in The book "Al-Ain" by Khalil Ibn Ahmad and "Al-Kitab" by Siubah, and finally, the main topic of the book is the similarities in the definitions, terms, and rules of the two mentioned languages. In the author's opinion, "these similarities are so close that it cannot be attributed to coincidence and some kind of historical relationship should be sought in this."
