The scope of the study is is: "vocalization and substitution" among the ancient Arab morphologists and the recent linguists.

The significance of the study comes from this linguistic and phonological handling; that confirms the impact of the "sound" in changing the structure of the word, whether it is a vocalization and its various sections or a substitution that is limited to some substitutable sounds with each other, or an influence from the Quranic reading that is followed by a change by this morphological structure.

The objectives of the present study are consistent with its branches of knowledge and requirements.

Moreover, searching for the differences of the recent linguists handling with the ancient Arab morphologists handling for this significant morphological phenomenon, which is (vocalization and substitution) according to the differences of the terms "letters" and "diacritics" and also according to the difference of the adopted method in each study of the different schools.

Ancient morphologists adopt "the standard method" as a basis in the analysis of the word structure, where contemporary linguists depend on the descriptive method" that interests in the Arabic word structure that does not consider "the virtual morphological origin" that is adopted by their ancient ancestors of the morphological balance of the word to consider the changes it happened.

At the conclusion, the study came up with a group of significant outcomes, most importantly: the importance of finding out the sounds of the word that made it up, its phonological syllables and the relationship between consonants and vowels; in order to revealing what occurs whether "vocalization" or "substitution" and its interpretation in the perspectives of both ancient morphologists and recent linguists.
