Knighthood is a special honor given to someone in recognition of their exceptional service, achievements, or contributions to their country. In medieval times, becoming a knight meant joining a warrior class: you trained with weapons, learned to ride horses in heavy armor, and swore oaths to protect the weak and serve your lord faithfully. Knights followed a code of behavior called chivalry, which emphasized courage, honor, and loyalty.

Today, knighthood works differently. In Britain, the King or Queen can grant someone a knighthood for accomplishments in fields like science, the arts, charity, or public service. When a man receives a knighthood, he becomes “Sir” (like Sir David Attenborough, the naturalist). A woman receiving the equivalent honor becomes “Dame.” The ceremony where someone receives their knighthood is called a dubbing, and it still includes the symbolic gesture of tapping the person's shoulders with a sword.

Modern knighthood doesn't come with armor or castles. It's purely an honor, a way of recognizing that someone's work has made a real difference. Scientists who make important discoveries, musicians who inspire millions, or people who spend decades helping others might all receive knighthoods.
