When someone is knighted, they are given a title that signifies their status. In the United Kingdom, for example, knights are typically referred to as "Sir" or "Dame" followed by their last name. They are also presented with a "knighthood insignia," which typically includes a ceremonial sword and a shield.
Becoming a knight is a great honor, and it is typically reserved for those who have made significant contributions to their field or society. It is a way of recognizing both one's past achievements and potential for future endeavors.
