Fulgently is an adverb that means to shine brightly or to radiate light. Synonyms for this word include brilliantly, radiantly, incandescently, luminously, dazzlingly, and resplendently. These words all suggest a sense of great brightness or light intensity. Alternatively, other words such as conspicuously, strikingly, and remarkably could be used as synonyms in non-literal contexts to describe something that stands out or attracts attention. Additionally, the term "glowingly" could also be used as a synonym for fulgently to denote an intense, vibrant light or aura around a subject.
