The word 闪耀 is formed by combining two characters, each contributing vivid imagery: 闪 depicts a person (人) momentarily framed in a doorway (门), evoking a sudden, fleeting burst of light or movement; 耀 combines light (光) with the element for a soaring bird (羽 over 隹), conveying the idea of brilliance radiating or spreading outward. Together, they create a dynamic compound where the first character suggests the instantaneous flash and the second character extends that into a shimmering, spreading radiance, perfectly capturing the essence of something glittering or dazzlingly bright.
