illustrious

This term carries a heavy weight of prestige and historical permanence. It describes a level of fame that is not merely popular or trendy, but earned through a lifetime of significant contributions or high status. It suggests a glow of excellence that inspires awe in others. While a person can be famous for a scandal, they can only be illustrious for their virtues or successes. It is most frequently used in formal biographies, academic introductions, or official ceremonies to signal a deep, institutional respect for someone's legacy.
