西部
xībù · HSK 3
western part
🌅 西 = west + 部 = part/region → western part
西 means west (think 'xi' in 西班牙 Spain). 部 means part, section, or region. Together 西部 literally reads 'west region' — the western part of a country, like the American West.
西 — top 覀 (cover) + bottom 儿 (legs); originally a bird in nest
Originally a pictograph of a bird settling into its nest at dusk. Because birds return to roost when the sun sets in the west, the character was borrowed to mean 'west.' The original 'nest' meaning was later written with 棲/栖.
部 — 阝(邑) right + 咅 phonetic
The right-side 阝 derives from 邑 (city/settlement), giving the meaning of a region, district, or administrative division. The left side 咅 supplies the sound. Originally referring to a settlement, the meaning broadened to 'part,' 'section,' or 'ministry.'
