division
📚 区 (district) + 分 (divide): a district split into parts = division, section
区 means area or district, and 分 means to divide or part. Together they describe dividing an area into sections, which gives the sense of classification or division.
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.
分 — knife 刀 + eight 八 (split apart)
分 originally depicted a knife (刀) cutting something into two parts, shown by 八 above (which itself meant 'divide'). The core sense is 'to divide' or 'split', from which extended meanings like 'portion', 'minute', and 'part' developed. Pronounced fèn, it carries the sense of an allotted share.
