淨 =
ㄐㄧㄥˋ · jìng
adj — clean, pure; (in compounds) net

字源 FORM — what the parts do

water
zhēng — gives the soundtwo hands pulling at one thing — "to contend"
ITzhēng → jìng — the same 爭 in 靜 jìng, 睜 zhēng
Water (氵) plus 爭. 說文 names it a clear pool at the north gate of Lu; 爭 lends the sound, worn from zhēng to jìng, and it sets 靜、睜 too. From the clear water, the everyday sense: spotless — 乾淨、淨化. The accounting "net" (淨重) rides on the same word.

故事 STORY — a scene to remember it by

一池清水(),髒東西全被)出去,剩下一片乾淨。
A clear pool (氵); every speck contended (爭) out of it — and what is left is clean.
