🔄 转 = rotate/turn + 换 = exchange/swap → turn-and-swap = transform
转 (zhuǎn) means to rotate or turn; 换 (huàn) means to exchange or swap. Together they form turn-and-swap, the act of converting one thing into another — change or transform.
转 — car radical 车 + 专 (phonetic)
转 is a semantic-phonetic compound. The left side 车 (cart/wheel) gives the meaning, evoking something that turns or rotates like a wheel. The right side 专 supplies the sound. Originally referring to the turning of a cart's wheels, it broadened to mean 'turn,' 'rotate,' or 'shift' in general.
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'.
