兜儿
dōur · HSK 7
to move in a circle
👜 dōur sounds like door — a pocket is a little door in your clothes
Open the door-pocket, drop things in. 兜 also means to circle around, like going through a revolving door and ending up where you started.
兜 — 白 (white) on top + 兒 base (child/legs)
兜 originally pictured a helmet or hood covering the head, with the upper part suggesting the headgear and the lower part showing a person beneath it. Over time the meaning broadened from 'helmet' to 'pouch' or 'hood-like pocket,' since both wrap around and hold something. Today it commonly means 'pocket' or 'to wrap up.'
