搓
cuō · HSK 7
to rub or roll between the hands or fingers
🤲 sounds like TSUO — twist-o your hands together to roll dough
The left radical 扌 means hand, and the right side 差 means difference. Your hands work against each other, creating friction as they rub and roll something between them — like shaping dough or twisting rope.
搓 — hand radical 扌 + 差 (chā, phonetic)
A semantic-phonetic compound. The hand radical 扌 signals an action done with the hands, while 差 supplies the sound (cuō is close to chā). The original sense is to rub or roll something between the palms, as in 搓手 'rub the hands' or 搓绳 'twist a rope'.
