Comparative study of single weak verbs in two semitic languages

The subject of comparative linguistic research is the comparison between the different languages belonging to a language family to determine similarities and differences in languages. The classification of language into Indo-European or Semitic languages family is the result of discovering similarities between different aspects of languages, including phonetic, syntactic and grammatical and morphological aspects that they originated from one original and were separated over time from the mother tongues. The main strategies of comparative linguistics are the comparison of phonological systems, understanding the history of lexical change, grammar and vocabularies of two or more languages in order to detection of similarities and differences between them; It is also useful for understanding the nature of human languages which are not static. The Arabic, Hebrew, Phoenician, Akkadian and Abyssinian languages have some basic common features that derived from the early Semitic principle called (Proto-Semitic). The Arabic and Hebrew languages of the Semitic language family are comparable in many respects; One of these aspects is the verb. In this research, descriptive weak verbs and their types in both languages are introduced by descriptive method, and then by mentioning examples from both languages, they are analyzed and adapted, and structural differences and similarities of weak verbs are expressed.
