Did You Know?
Illustrious people seem to light up everything around them. The etymology of illustrious makes it clear that a shining glow (both literal and figurative) has long been associated with the word. “Illustrious” ultimately derives from the Latin verb lustrare, which means “to purify” or “to make bright,” and which is related to the noun that gave us “luster.” At one time, “illustrious” was used in the literal sense of “shining brightly with light,” but that meaning is now considered archaic. The word is now almost exclusively used in its figurative application to describe something that stands out brilliantly, much like a bright star stands out in the sky. – www.merriam-webster.com
