符
ㄈㄨˊ · fú
noun — a tally, token, credential; a symbol, charm
字源 FORM — what the parts do
Tfù → fú — tone shifts
A strip of bamboo (竹) split in two, the halves matched to prove a claim — the tally. 付 fù carries the sound and a fitting picture: one hand handing a thing across (亻 + 寸). The two halves must hand back into each other. From the matched tally: 符號、相符、護身符. 付 builds 府、附、咐.
故事 STORY — a scene to remember it by
半片竹（竹）遞過去（付），跟另一半一合，嚴絲合縫——對上了。
One half of the bamboo (竹) is handed over (付); it meets the other half and the edges close — they match.
