Radiant
adjective /ˈreɪdiənt/ — Emitting light or warmth — and, by extension, the quality of someone whose inner state shines outward.
Definition
Sending out light; shining or glowing brightly; (of a person) clearly emanating great joy, love, or health — the inner state visible in the outward glow.
Beyond the definition
Radiant is the word for joy you can't hide — happiness so present that it changes the quality of the air around someone. The word does double duty: it describes literal light and the metaphorical light of someone who is genuinely, visibly alive.
Origin & history
From Latin radians — emitting rays (from radiare: to emit beams, from radius: ray). The image: rays extending outward from a source, impossible to contain.
