朱
ㄓㄨ · zhū
noun/adj — vermilion, cinnabar red; a surname
字源 FORM — what the parts do
一形a mark struck through the trunk — pointing at the red heart of the woodan indicating stroke (指事), not a separate thing
A tree (木) with a stroke laid across its middle — the mark points at the red heartwood inside the trunk. From that red core came the colour: vermilion, cinnabar red. The trunk sense lives on in 株; the colour took over the rest. As a sound it builds 株、珠、誅.
故事 STORY — a scene to remember it by
把樹（木）攔腰一劃，劈開看——芯是紅的，朱。
Strike a mark across the tree (木) and split it: the heart is red — 朱.
