Which word characterizes someone marked by honor, courtesy, and courage?

The word that characterizes someone marked by honor, courtesy, and courage is "chivalrous." This term traditionally refers to the qualities associated with knights, particularly in the context of medieval ideals. Chivalry encompasses a sense of duty to be honorable, uphold high moral standards, and show respect and politeness, especially towards women. It embodies courage in the face of adversity as well.

While "brave" also conveys a sense of courage, it does not fully encompass the aspects of honor and courtesy embedded in chivalry. Similarly, "gentle" suggests a kindness and mildness but lacks the connotations of courage. "Gallant" is a close synonym and can imply bravery and courteous behavior, often in romantic contexts, yet it still falls short of the comprehensive nature of "chivalrous," which integrates honor and a broader code of conduct. Thus, "chivalrous" is the word that best captures the essence of someone who exemplifies these noble traits.
