A captain is a leader in charge of a group, often in a sports team or on a ship. In sports, the captain motivates teammates and makes important decisions during the game. On a ship, the captain ensures the safety of the crew and passengers while navigating through waters. Captains are responsible for guiding their teams or vessels toward success. They must communicate well and inspire trust among their members. Whether it's a football team or a sailing boat, a good captain plays a crucial role in achieving goals and overcoming challenges together.
