枕头
zhěn tou · HSK 7
pillow
🛏️ 枕 (pillow) + 头 (head) = the thing your head rests on at night
枕 already means pillow or headrest; 头 means head. The pairing literally names the head-support you sleep on. Pronounced zhěn tou, with the neutral-tone 头 you also hear in many body or object words.
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'.
