Akkadian Origin Theory Language study

The Akkadian language is one of the most important Semitic languages linguistically and culturally, and there is a section of researchers who believe that the Akkadian is (the gracious mother) of the group of Semitic languages, and from it the rest of the languages of this group branched off, and this research tried to shed light on this saying and explaining what it has and what it has.
The research has proven that Standard Arabic and Akkadian are neither (origin and branch) nor (language and colloquial), but rather they are two dialects of the mother tongue, and they are close to each other, The partial similarity between the two languages came by virtue of proximity and belonging to a common ancient linguistic origin (mother tongue). Just as there are similarities between the two languages, there are also differences, especially in the phonetic aspect.
