障 ＝ 阜 ＋ 章
ㄓㄤˋ · zhàng
noun/verb — a barrier; to block, obstruct
字源 FORM — what the parts do
阜義a mound, a wall of earth (阝)
Tzhāng → zhàng — the tone shifts
A bank of earth (阝) thrown up to cut one side from the other — a barrier. 章 zhāng carries the sound, the tone fallen to zhàng. From the blocking wall come 屏障 and 障礙; what gets in the way is a 障礙物.
故事 STORY — a scene to remember it by
路前堆起一道土埂（阝），把人和那邊隔開——過不去了。
