Root Breakdown

=radiant

radi (ray) + -ant (adj. 'doing X') = 'sending out rays.' Literally it describes anything that beams light or heat—a radiant sun, radiant heat. The metaphor is irresistible: a happy or healthy person seems to give off light, so a radiant smile or radiant bride 'shines' the same way.
