市区
shìqū · HSK 4
urban area
🏙️ 市 (market) + 区 (district) = the market district = urban area
市 means market or city; 区 means district or zone. Together they name the built-up district where commerce happens — the city proper, as opposed to suburbs or countryside.
市 — top 亠 + cloth 巾
Originally a pictograph of a marketplace banner or sign post above a stall, indicating a place of trade. The character came to mean 'market', and by extension 'city' or 'town', since markets were the centers of urban life. The modern form combines a top stroke with 巾 (cloth/banner).
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.
