燿

To shine or dazzle; describes something as brilliant or radiant.

Functions primarily as an adjective or a verb of state. It rarely serves as a noun for "light" itself, focusing instead on the act of shining or the attribute of radiance.

Carries a connotation of intensity—such as a glare or shimmering heat—rather than steady light (e.g., 明). While often used interchangeably with 曜, 燿 (fire radical) more typically suggests terrestrial fire or combustion, whereas 曜 (sun radical) generally denotes celestial bodies or stable luminescence.

Frequently used as a semantic variant of 曜.
