付 — person radical 亻 + hand 寸
付 originally pictured a hand (寸) reaching out to hand something to a person (亻), depicting the act of giving or delivering. The core sense 'to hand over, deliver, pay' has remained stable since ancient bronze inscriptions. It also serves as a phonetic component in characters like 附, 符, and 府.
