infrastructure
UK: ˈɪnfrəstrʌktʃə | US: ˈɪnfrəˌstrʌktʃər
n. the basic physical and organizational structures and facilities (e.g., buildings, roads, power supplies) needed for the operation of a society or enterprise.
The word "infrastructure" combines the Latin prefix infra- (meaning "below" or "beneath") with structure (from Latin structura, meaning "a building" or "framework"). Originally used in military contexts (early 19th century) to describe permanent installations supporting operations, it later expanded to civil engineering and societal systems. The term reflects the idea of foundational, often hidden, systems that enable larger functions—much like a substructure beneath visible architecture.
