to disintegrate
🧩 解 dismantle + 体 body = take a structure apart into its pieces
解 means to untie, loosen, or take apart; 体 is body or structure. Together: a body broken down into its components, hence to disintegrate or collapse. Compare 解决 (solve) where 解 also means to break a problem apart.
解 — horn 角 + knife 刀 + ox 牛
解 is an ideograph showing hands using a knife (刀) to separate the horn (角) from an ox (牛). The original meaning was to butcher or dismember an ox, which broadened to 'untie, separate, loosen,' and then extended figuratively to 'explain' or 'understand'—to take something apart mentally.
