ㄧㄣ · yīn
noun — a sound; a tone
字源 FORM — what the parts do
音形言 (speech) with a mark (一) set in the mouth; the strokes later settled into 立 over 日
音 began as 言 (speech) with a mark (一) inside the mouth — 說文: 從言含一; the sound held an instant before it becomes a word. Centuries of copying settled the strokes into 立 over 日. The bare sound: 聲音; sound put in order: 音樂; the sound a place leaves in a mouth: 口音.
故事 STORY — a scene to remember it by
嘴一張（言），先含住一（一）個聲——話還沒出口，音先在。
The mouth opens (言) and first holds a single sound (一) — before the word, the tone is already there.
