In some types of speeches, it can be especially effective to end with a statement or question that drives home your main point. This rhetorical device is important for conclusions because you want to emphasize the points you made during your speech and have the audience feel connected to your ideas. For example, you might end a speech explaining how to change the oil in your car with a simple statement that sums up your thesis: “Remember, the best way to protect your car is to change the oil every three thousand miles—and it’s something you can do yourself.”
