陷
陷 ＝ 阝 ＋ 臽
ㄒㄧㄢˋ · xiàn
verb — to fall into, sink into; to frame, trap
字源 FORM — what the parts do
阝義a mound, ground
臽聲xiàn — a person falling into a pit (a hand 𠂊 above the mortar-pit 臼)also carries the meaning: the trap itself
Ground (阝) and 臽 xiàn, which is itself a person dropping into a pit — a hand above, the pit-hollow below. The component both names the sound and shows the fall. From the pit: to sink in (陷入), and the dug trap that catches a victim (陷害).
故事 STORY — a scene to remember it by
腳下的土（阝）一塌，人就順著臽的坑口直直墜下去。
The ground (阝) gives way, and down the pit-mouth of 臽 the body drops straight through.
