腹部

abdomen
🤰 腹 = belly + 部 = part/section; literally 'belly section'
腹 (fù) means belly or abdomen; 部 (bù) means part, section, or department. Together they name the belly region of the body. The same 部 appears in 部门 (department) and 全部 (entirely).
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.'
