弟
ㄉㄧˋ · dì
noun — younger brother
字源 FORM — what the parts do
弟形a cord wound down a stake, turn under turn — the old graph
A cord wound around a stake, each turn under the last — sequence. The order of the winding became the order of brothers, and the word settled on the one who comes after: 弟弟. Sequence itself moved out under a bamboo hat: 第.
故事 STORY — a scene to remember it by
繩子一圈一圈往下繞——誰先誰後，看得清楚。
The cord winds down the shaft, turn under turn — who is first, who is next, plain to see.
