The kanji 複 is a phono-semantic compound (形声文字; keisei moji). It is composed of two parts: ⚫︎ The phonetic component: 复 (fuku/fu, meaning "to repeat; again"). This provides the sound element. ⚫︎ The semantic component: 衣 (i, meaning "clothing; clothes"). The combination implies that the clothing is folded or doubled over, leading to the meaning of "multiple" or "double." This association with doubling or repeating led to the broader meaning of "complex" and "multiple".
