resplendent (adj.)

mid-15c., of color, "shining brilliantly, splendid, very bright," from Old French resplendant and directly from Latin resplendentem (nominative resplendens) "brilliant, radiant," present participle of resplendere "to glitter, shine brightly," from re-, here perhaps an intensive prefix, + splendere "to shine, be splendid" (see splendid). In 16c.-17c. often resplendant. Related: Resplendently.
