Most papers written on polysemy focus on sense overlaps and lexical ambiguity, yet studies that explore the possibility of establishing a polysemic complex and explaining how the new interpretations arise through metaphor are almost non-existent in Arabic. This paper aims to explore how metaphor serves to create new concepts as part of polysemic complexes through adopting Dynamic Conceptual Semantics. The target words are bidʒannin [make mad][1] in Jordanian Arabic (JA) and mad in American English (AE). An online questionnaire containing 15 items was sent to forty participants (20 JA speakers and 20 AE speakers) where they were asked to provide the interpretations of the words bidʒannin and mad in contextualized sentences. The AE contextualized instances of mad were collected from Corpus of Contemporary American English (COCA) which generated 5,168 tokens of mad (in the years 2015/2019). The questionnaire results were discussed in a semi-structured focus-group discussion involving 10 participants. We have demonstrated that when an expression is deemed suitable for all situations categorized under both the primary perspective of madness and a related perspective involving exaggerated descriptions of entities, a concept (P) emerges that bears similarity or relevance to the polysemic complex ( bidʒannin\mad ) to which the expression belongs. In such cases, we can consider the related perspective (P') as a member of the polysemic complex ( bidʒannin\mad ). Thus, this study explains how the same metaphor can lead to a complex of multiple meanings in two different languages that are not necessarily related to each other.
