A monopoly means that one company or person has complete control over something, like a product or service. They are the only ones who can offer it and compete against them is very difficult. For example, if there was only one store that sold a popular game, they would have a monopoly on the game because no other store could sell it. It's important to recognize a monopoly because it can sometimes lead to higher prices or less choice for consumers.
