What changes in word structure are taken into account and what is not in morphological equivalence.

Abstract

Arab scholars adopted the morphological scale as a tool to represent the structure of words subject to the rules of Arabic morphology. They chose the letters fa, ain, and lam as letters to represent the first, second, and third roots of words They also established rules for representing more than three letters in the root word, and they also established rules for expressing additions and deletions that affect the structure of the original word. However, when establishing these rules, they stated that some changes that occur in the structure of the word must be taken into account in the scale, and that some of these changes are not taken into account.

The aim of this research is to explain the changes that are taken into account in the balance and the changes that are not taken into account, and to explain the scholars’ statements on them while giving appropriate examples of them. The method followed in this research is the descriptive analytical method that is capable of achieving the objectives of this research by describing these changes, giving examples of them, and analyzing them.
