(a.) Beaming with vivacity and happiness; as, a radiant face.
(a.) Giving off rays; -- said of a bearing; as, the sun radiant; a crown radiant.
(a.) Having a raylike appearance, as the large marginal flowers of certain umbelliferous plants; -- said also of the cluster which has such marginal flowers.
(n.) The luminous point or object from which light emanates; also, a body radiating light brightly.
