Tips

register
The lēi reading is colloquial spoken Mandarin - used when a rope, belt, strap, or tie physically digs into something. Written/literary contexts and almost every compound take the sister reading lè instead (勒令, 勒索, 勾勒, 悬崖勒马). If the sentence describes a physical strap squeezing flesh, it is almost always lēi.

Components

radical
strength; force
Right - pictograph of a flexed arm or a plow muscled into the soil, meaning strength/force. Indexing radical here. Combined with the picture is a leather strap pulled tight by force - exactly the rein-in / restrain / engrave senses of .
semantic
leather; hide
Left - pictograph of a stretched animal hide (head, body, four limbs). The original meant a leather bridle for a horse, so the leather radical anchors the sense. Family: (shoe), (saddle), (whip) - all leather goods. The leather strap is what does the restraining.
