What is the function of paddle?

A paddle is a tool used primarily for propulsion in watercraft, such as canoes and kayaks. It consists of a long shaft with a broad blade at one end, allowing the user to push against the water to move the craft forward or steer it. Additionally, paddles can be used for other purposes, such as mixing or moving materials in cooking or construction. Overall, the main function revolves around facilitating movement and control in various fluid environments.
