抠
koū · HSK 7
to pick out
🤏 扌 hand + 区 qū (phonetic) = fingers digging or picking something out
The 扌 hand radical carries the meaning of finger-work, while 区 (qū) supplies the koū-ish sound. Colloquially 抠 also means stingy, as in someone who picks over every cent.
抠 — hand radical 扌 + 区 (qū, phonetic)
A semantic-phonetic compound: the hand radical 扌 signals an action done with the hand, while 区 supplies the sound (qū → kōu). The original sense is to dig out or gouge with the fingers, which extended figuratively to 'stingy' — picking out tiny amounts as if scraping them free.
