率
ㄌㄩˋ · lǜ/shuài
noun — rate, ratio; (shuài) verb — to lead, command
字源 FORM — what the parts do
率形rendered bare — a net strung on a frame, threads to either side
A net stretched on its frame, cords trailing off both sides — the old graph is a bird-net. From holding the net's lead-line: to lead, to command (shuài). From the catch counted against the throws: a rate, a ratio (lǜ). One graph, the two readings split along these two senses.
故事 STORY — a scene to remember it by
一張網架好，手抓總繩一帶——後面的全跟著走。
A net rigged on its frame; one pull on the lead-cord — everything behind it follows.
