脱身
tuō shēn · HSK 7
to get away
🏃 脱 shed/slip-off + 身 body = slip your body out of a situation
脱 means to shed or take off (as with clothes or skin); 身 is the body. Together they mean to slip your body free — to get away from obligations or disengage from a tricky spot, the way a snake sheds its skin and moves on.
脱 — flesh radical 月 (肉) + 兑 tuì (phonetic)
脱 is a semantic-phonetic compound. The flesh radical 月 (from 肉) signals the body, while 兑 supplies the sound. Originally it meant shedding flesh or skin, like a snake molting, and broadened to mean 'to take off, slip off, or escape.'
身 — pictograph of a pregnant body
身 is a pictograph originally depicting a person with a swollen belly, representing a pregnant woman in profile. Over time the meaning broadened from 'pregnancy' or 'torso' to refer to the body in general, and by extension oneself or one's person.
