region-wide

The compound adjective 'region-wide' is a modern English formation following a common pattern of combining a noun with the adjective 'wide'. The noun 'region' originates from Latin regio, meaning a direction, boundary, or district, derived from the verb regere meaning 'to direct, rule'. The adjective 'wide' has Germanic roots, from Old English wīd, meaning broad or spacious. When combined, the literal sense is "broad as a region" or "extensive across a district," which logically evolved into the modern abstract meaning of something encompassing an entire geographical or administrative area. This pattern mirrors other similar compounds like 'nationwide' or 'worldwide', where 'wide' acts as a scope-extending suffix.

Structure: region (area) + wide (broad) - region: From Latin regio (direction, boundary, district), via Old French. In this compound, it functions as a noun stem specifying the scope. - wide: From Old English wīd (spacious, extensive). In this compound, it functions as an adjective meaning 'extending over the whole area'.
