In literature, the term "regional" is employed with notable versatility, functioning both as a descriptor of geographical areas and as a qualifier for socio-political, economic, and scientific phenomena. For example, "regional" is used to denote specific subdivisions or areas within a larger whole, as seen in texts discussing regional maps and surveys that capture localized variations in culture, climate, or resources [1, 2, 3]. In political and economic discourses, authors invoke "regional" to highlight distinctions in governance systems or trade dynamics, illustrating how certain parties or economies become influential within defined territories [4, 5, 6]. Additionally, in technical and administrative accounts, the adjective appears in contexts ranging from regional organizational structures and educational committees to specialized fields like regional anesthesia or the distribution of natural formations [7, 8, 9, 10]. Overall, "regional" helps writers articulate the unique characteristics and complex interrelationships that emerge in localized settings, bridging the gap between the specific and the universal.
