雨

Rain; rainy. May denote "the rainy season" or a specific period of rainy weather in calendars or lists of natural phenomena.

Functions as a noun, adjective, or verb (to rain; to fall as rain). In classical syntax, it often functions as the action itself without requiring an auxiliary verb such as //jiang// (降).

Tang-period reading: *hiǒ. Specialized semantic variant: U+99AD.

Kangxi radical 173. When appearing as the upper component of a character (e.g., 雪, 雲, 雷), it serves as a category marker for celestial or atmospheric phenomena.

In philosophical or political texts, precipitation often functions as a signifier of cosmic harmony, the "Mandate of Heaven," or the virtue of the ruler; conversely, drought or excessive rain typically signals divine disapproval or systemic disorder.
