Fulgur lightning flash is the fire that flashes from the fulmen thunderbolt: whence fulgetrae lightning flashes and fulgor brightness/glitter are also named; as Virgil in book V:

IURGIUM quarrel/dispute and LIS lawsuit/legal dispute have this distinction. Iurgium is a lighter matter; since among benevolent people or relatives, a discussion or contention is called iurgium; among enemies, a dissension is called lis. M. Tullius Cicero in On the Republic, book IV: "I admire not only the distinction of things, but also the elegance of the words. 'If they quarrel original: "iurgant",' he says: the contention of benevolent people is called iurgium, not the lis lawsuit of enemies." — And in the following: "The law, therefore, thinks that neighbors should quarrel original: "iurgare" with each other, not litigate original: "litigare"."

AVDACIA audacity/rashness and AVDENTIA courage/boldness are different in that audacia belongs to rashness, audentia to fortitude. Sallust in the War of Catiline: "Audacity original: "audacia" is held as a wall." — Virgil in the Aeneid:
