淇
淇 ＝ 氵 ＋ 其
ㄑㄧˊ · qí
noun — a river name; (in 冰淇淋) ice cream
字源 FORM — what the parts do
氵義water — it names a river
Water (氵) plus 其. 其 was a winnowing basket, long borrowed off to write "its"; here it lends the sound qí, the same it gives 期、棋、旗. 說文 names 淇 a river out of the northern hills. The watery river-name later got pulled into 冰淇淋 for ice cream, purely for the sound.
故事 STORY — a scene to remember it by
一條水（氵）打從北邊山裡淌出來，岸邊一只簸箕（其）擱在石上。
A river (氵) runs down out of the northern hills; on a rock at its edge sits a winnowing basket (其).
