取 — ear 耳 + hand 又
取 originally depicted a hand (又) grasping an ear (耳), referencing the ancient practice of soldiers cutting off enemies' left ears as proof of kills to claim rewards. The meaning broadened from 'seize/take by force' to the general sense of 'take, get, obtain' used today.
混 — water radical 氵 + 昆 (kūn, phonetic)
A semantic-phonetic compound: 氵 (water) gives the meaning, while 昆 supplies the sound. The original sense was waters mingling or flowing together, which extended to 'mix, blend, confuse.' Modern uses like 混乱 (chaos) and 混合 (to mix) preserve this core idea of things merging.
