律
律 ＝ 彳 ＋ 聿
ㄌㄩˋ · lǜ
noun — rule, law; pitch, rhythm
字源 FORM — what the parts do
彳義a step — the road
聿聲yù — a hand holding a brush; gives the sound
I≠yù → lǜ — the initial alone reshapes
A hand with a brush (聿) writes; the road (彳) is where everyone walks — conduct set down in lines. 聿 yù also carries the sound, the initial worn to l. The word first named the pitch-pipes that fixed the twelve tones (十二律); one fixed standard became every fixed standard: 法律、規律.
故事 STORY — a scene to remember it by
筆（聿）落下去，一條一條寫好；路上（彳）的人，照著走。
The brush (聿) sets down line after line; on the road (彳), the walkers keep to them.
