字源 FORM — what the parts do
朱聲zhū — gives the sound朱 was itself the trunk-and-red-heart graph; the wood radical pins it back to the trunk
Wood (木) plus the sound 朱 (zhū) — the trunk, the stump rooted in the ground. Because each stump is one rooted plant, 株 became the counter for them: 一株樹. The old idiom 守株待兔 — waiting by the stump for another hare — is this very stump.
故事 STORY — a scene to remember it by
樹（木）砍掉了，剩下紮在土裡的那一截樁——一株。
The tree (木) is cut; what stays rooted in the earth is the stump — one 株.
