area
🗺️ 区 = zone/ward + 域 = domain/territory
区 means a divided section or ward; 域 means a bounded domain or territory. Together 区域 stacks two near-synonyms meaning a demarcated area or region. Common in admin terms like 行政区域 (administrative region).
区 — enclosure 匚 + 品 (items)
Originally a pictograph of items (品) hidden inside a container (匚), meaning to store or conceal. The sense extended to a bounded space, then to an administrative district or area. As a surname read Ōu, it preserves the older 'hidden/enclosed' nuance.
