TSUMUGU · TOCFL B1 (est.) · 字
薄
薄 ＝ 艸 ＋ 溥
ㄅㄛˊ · bó/báo
adj — thin, slight; meager; (báo) thin (of layers)
字源 FORM — what the parts do
艸義grass (艸) — the plant radical, written 艹
溥聲pǔ — gives the sound
{b,p}Ipǔ → bó — the p/b crossing
Grass (艸, written 艹) for plants; 溥 pǔ — water spread wide — carries the sound, worn toward bó. 說文 reads 薄 as dense thicket (林薄); the everyday word turned the other way to thin, slight, meager: 薄紙, 微薄, with the spoken báo for a thin layer.
故事 STORY — a scene to remember it by
一張薄薄的紙（艹），對著光幾乎透過去。
A sheet of paper thin (艸) enough to all but see the light through.
