The kanji 変 is a phono-semantic compound (形声文字 - keisei moji). The left side is 攴 or 攵 (boku or bun), which is a component signifying "to tap" or "to strike" suggesting an action that induces or facilitates change. The right side is 䜌 (ben), a complex component suggesting a tangled or complicated state. Combined, these components create the meaning of "to change" or "to transform," implying that an action causes something to become complex or different from its original state. The upper part of 䜌 is also used in the character for "silk" or "thread", hence an implication of how thread can change its appearance or position by being tangled up.
