Luminous
Emitting or reflecting light; radiant
Light From Within
A candle flame glows. The moon lights up the night sky. A firefly pulses in darkness. These are luminous—they emit or reflect light, creating a gentle radiance.
The word comes from Latin lumen (light). Something luminous doesn't just have light on it—it seems to radiate light, to glow from within.
