About
The character "霪" is formed from the semantic radical "雨" meaning rain and the component "淫" which provides phonetic guidance and contributes its associated sense of overflow or surplus, together specifying the meaning of incessant or excessive rainfall. This character originated to distinctly describe prolonged rainy conditions, and its usage has historically been confined to this meteorological context, with the arrangement of "雨" above "淫" constituting its enduring written structure.
