to lie on one's stomach
🛌 趴 = 足 foot + 八 eight; pā sounds like flopping pat-down face-first onto a desk
The 足 (foot) radical marks a body posture; pā is the soft pat sound of leaning your upper body down onto a desktop. In Taiwan it doubles as percent (the % sign leaning over).
趴 — foot 足 + phonetic 八
趴 is a phono-semantic compound. The foot radical 足 hints at posture or body position, while 八 (bā) supplies the approximate sound, later shifted to pā. It came to mean lying face-down or sprawling, extending to leaning or bending over a surface.
