勒
ㄌㄜˋ · lè
verb — to rein in, strap tight; to force, extort; to carve
字源 FORM — what the parts do
IFT≠lì → lè — the reading shifts wide off the donor
A leather strap (革) drawn tight over a horse's head — the bridle, hence to rein in and to force. 力 lì carries the sound, the reading shifted far off to lè. From pulling the rein come 勒索 (to extort) and 勒石 (to carve into stone).
故事 STORY — a scene to remember it by
皮韁（革）猛地一勒，那匹馬硬生生被拉住了頭。
The leather rein (革) snaps taut and yanks the horse's head to a hard stop.
