藏
藏 ＝ 艸 ＋ 臧
ㄘㄤˊ · cáng/zàng
verb — (cáng) to hide, store away; noun — (zàng) a storehouse, treasure
字源 FORM — what the parts do
艸義grass (艸) — the plant radical, written 艹
臧聲zāng — gives the sound
IFzāng → cáng — initial and final shift; the zàng reading stays nearer
Grass (艸, written 艹) to cover something over; 臧 zāng — to put away safe — carries the sound and its own sense of storing. 說文 reads 藏 as to conceal: 躲藏, 收藏. Read zàng, the noun is what is stored — a hoard, 寶藏, and 西藏.
故事 STORY — a scene to remember it by
把東西埋進草（艹）裡蓋好，誰也找不著。
The thing tucked into the grass (艸) and covered — and no one can find it.
