Etymology
The word interregional is a modern English formation built from classical components. The prefix inter-, from Latin, establishes the core concept of reciprocity or spatial relationship between entities. It is attached to the noun region, which itself derives from the Latin regio, related to regere meaning "to direct or rule", originally implying a bounded administrative or geographical territory. The suffix -al then converts this compound noun into an adjective. Thus, the literal construction "relating to between regions" logically yields the modern abstract meaning pertaining to connections, comparisons, or movements across different geographical or administrative areas.
