换 — hand radical 扌 + 奂 huàn (phonetic)
换 is a semantic-phonetic compound. The hand radical 扌 signals an action done with the hands, while 奂 supplies the sound huàn. The original sense of exchanging or swapping things by hand extended naturally to broader meanings like 'change' or 'replace'.
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.
