💡 理 = reason/logic + 解 = untie/解 解 = solve; reason out + unravel = understand
理 originally meant the grain in jade — patterns you follow to cut cleanly; it now means logic/principle. 解 shows a knife 刀 separating a horn 角 from an ox 牛 — to untie or solve. Together: follow the logic and untie the knot = comprehend.
理 — jade radical 玉/王 + village 里 (phonetic)
理 is a semantic-phonetic compound: the jade radical 王 (玉) on the left signals meaning, while 里 on the right gives the sound. It originally meant the natural veins or grain in a piece of jade, then extended to 'pattern,' 'order,' 'principle,' and finally the modern senses 'reason' and 'to manage.'
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.
