A pennant is a type of flag that is typically triangular in shape and used for various purposes, including signaling and decoration. In sports, especially in baseball, a pennant often represents a championship title or a team's success in a particular season. Pennants can also be used in maritime contexts, where they serve as signals for ships. They may convey specific messages or indicate a ship's nationality. Additionally, decorative pennants are popular in celebrations and events, often strung together to create festive displays.
