interrégional

Interrégional is a French adjective describing relations, actions, or phenomena that involve more than one region or cross regional boundaries. It is commonly used in geography, urban planning, public administration, economics, and transport policy to indicate cooperation, planning, or connections that span regional jurisdictions rather than being confined to a single region. In transportation, for example, interrégional networks connect different regions through roads or rail lines, while in economic development the focus may be on interrégional projects and shared services.

Etymology and forms: the term derives from the prefix inter- meaning “between” and région meaning “region.” The feminine form is interrégionale, and the plural forms are interrégionaux (masculine) or interrégionales (both genders). As a descriptor, interrégional can modify nouns such as coopération, coopération interrégionale, planning interrégional, or réseau interrégional.

Contexts and usage: interrégional relations may be formalized through agreements between regional authorities, cross-boundary initiatives, or participation in programs that promote regional integration. In the European context, the term is often encountered in discussions of interregional cooperation programs (such as EU Interreg) that fund projects spanning multiple regions. It also appears in cultural, educational, and sports contexts to denote events or activities that involve participants from several regions.

See also: interregionalism, cross-border cooperation, regional planning, territorial cohesion, Interreg. In English-language usage, the equivalent term is interregional.
