Most characters — around four in five — are built this way: one part hints at the meaning, the other at the pronunciation.

This origin belongs to the traditional form 汙; 污 is its simplified writing.

The traditional form 汙 pairs 水 (water) with 于 for the sound; the simplified 污 is a later shorthand.
