膽 character · TOCFL B2 (est.)
膽 ＝ 月 ＋ 詹
ㄉㄢˇ · dǎn
noun — the gallbladder; courage, nerve

字源 FORM — what the parts do

月義flesh (肉) — the body organ radical, written 月
詹聲zhān — gives the sound
IFzhān → dǎn — initial and final both reshaped
Flesh (肉, written 月) names the organ — 說文 sets the gall against the liver. 詹 zhān carries the sound, worn toward dǎn. Old physiology seated boldness in the gall, so 膽 means nerve as much as the organ: 大膽, 膽量, 膽小.

故事 STORY — a scene to remember it by

肝（肉）邊掛著一枚膽——人的膽子，就藏在這裡。
Beside the liver (肉) hangs the gall — and a person's nerve is kept right there.
