IFTyú → wū — the donor reading drifted off
Stagnant water (氵) gone foul — dirty. 于 yú carries the sound, worn far from the modern reading. From filthy water the word spreads to anything soiled: 污染、污點、貪污.

一灘不流的水（氵），浮著綠苔，湊近就皺眉。
A patch of standing water (氵), green scum on top — you lean in and wince.
