The issue of terminology is one of the most challenging aspects in specialized lexicography in Arabic. In general, many terminological units in Arabic lexical systems have yet to reach a stage of stability or achieve unified efforts toward developing a comprehensive and standardized terminological dictionary. This situation has resulted in the lack of consensus on key dimensions, leading to the fragmentation of terms and concepts due to the multitude of references. In Arabic, phrasal verbs exhibit diverse terminological sources, ranging from foreign linguistic references (such as French and English) to classical Arabic heritage. As a result, the term has generally been approached by scholars from multiple perspectives, both in terms of terminology and conceptual structure. This is partly due to the prevalence of ambiguous terms that are challenging to define and abstract, as well as the varied interpretive frameworks applied to them. This study explores the issue of creating theatrical terminology in the Arabic language and examines how it can be addressed in specialized dictionaries. It highlights the importance of unifying theatrical terminology and providing reliable, up-to-date resources for professionals in the field. Furthermore, it showcases the specialized dictionaries and glossaries that have been developed while discussing the challenges encountered in these efforts, such as difficulties in translating terms from foreign languages and insufficient coordination among stakeholders.
