Well-known, highly respected, and admired for past achievements and noble character.

Illustrious is a grand, dignified word. It is reserved for people with long, brilliant careers of high historical or cultural significance.

The story behind the word. Illustrious shares its roots with 'illustrate' and 'luster' (shine). It comes from the Latin 'illustris', which literally meant 'bright, clear, or illuminated.' An illustrious person is someone who is so brilliant in their achievements that they seem to cast a warm, glowing light on everyone around them.
