The sounds constitute the raw material from which languages are composed to express the depths of the psyche, serving as a means of human communication. Arab scholars have consistently emphasized the role of these sounds. Some considered language, as exemplified by figures like Ibn Jinni, to be sounds themselves. Others regarded them as linguistic directions and rules, upon which they based the analysis of linguistic changes arising from alterations such as elision or substitution. Thus, the researchers chose to investigate the role of phonetics and its correlation with the morphological level, and its impact on morphological paradigm. Morphology attends to the individual structure, formulation, and composition of words, while phonetics constitutes the raw material of those utterances, encompassing consonants and vowels. The study was structured into an introduction and two sections. The introduction defined linguistic concepts, while the first section addressed the influence of phonetics on morphological paradigm. The second section explored morphological paradigm and its susceptibility to phonetic factors. The researchers arrived at several conclusions:

1. The significance of both types of sounds (consonants and vowels) lies in their capacity to transform the morphological paradigm, altering its standardized form to an alternate one. Additionally, the Arabic language is characterized by its cohesive system and interconnected parts, with sound serving as the foundational building block. Words are formed from it, enabling each community to express its essence.
2. Scholars’ discourse on linguistic issues and their justification leans towards logical reasoning and scientific thought to establish criteria that preserve linguistic authenticity amidst variations and errors. Their approach is both analytical and descriptive.
3. Sound has been a reason for scholars to resort to its study in order to explain certain morphological matters, highlighting its impact on morphological paradigm and other aspects.
4. The weightiness or pursuit of lightness resulting from phonetic nuances has been an influential factor in altering the morphological paradigm, shifting it from its measured form to a form necessitated by the pursuit of ease in pronunciation.
