头部
tóubù · HSK 7
head
👤 头部 = 头 (head) + 部 (part/section) = the head region
头 means head and 部 means part or section, so 头部 is literally the head part of the body. 部 is the same section word in 部分 (part) and 部门 (department).
头 — 页 (head/page) + 豆 (bean, phonetic)
The traditional form 頭 combines 頁 (xié), meaning 'head', with 豆 (dòu) as the phonetic component. 頁 itself originally depicted a person with an emphasized head. The simplified form 头 is a modern shorthand that replaces 豆+頁 with a simpler shape while keeping the same meaning of 'head' or 'top'.
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.'
