Mahmoud Zamakhshari's "comprehensive" work as the basis of later grammatical theories

Despite the fact that there are many works on Arabic grammar, which are perfect and known for their content,  the  work  of  Zamakhshari  “ لصفملا”  is  considered  by  his  contemporaries  "the  best  book  on  Arabic grammar"1 . Another scientist compares it with “fine-grained durga” 2. This work has great historical importance due to the laconic and clear interpretation.  The issues raised in Zamakhshari's work testify to the development of Arabic linguistics at that time. In the play, we see the achievements of the 12th  century through the coverage of grammatical issues.  A “Mufassal” is an aggregated and refined review of research conducted prior to this work.  When creating "Mufassal" Zamakhshari pursued not only a scientific goal, but also its convenience. This aspect allowed him to become one of the most famous works. Zamakhshari, as a linguist well versed in the theory of Arabic grammar, managed to compose the book in his own way.
