Resembling or producing a flash of lightning; characterized by sudden brilliance or brightness.
From Latin fulgor 'lightning, brightness' plus the English adjectival suffix -ous. The suffix -ous derives from Latin -osus, a common ending for adjectives. This word emphasizes the flashing, lightning-like quality of brilliance rather than steady radiance.
Notice how fulgorous emphasizes the sudden, dramatic quality—like lightning—while fulgent suggests a steadier, more sustained brightness. English uses different suffixes to shade meaning: -ous often implies something more intense or sudden, while -ent suggests a continuous state.
