Monopoly means a market where there is only one seller of a particular good or service.In economics, a monopoly (from the Latin word monopolium – Greek language monos, one + polein, to sell) is defined as a persistent market situation where there is only one provider of a product or service. Monopolies are characterized by a lack of economic competition for the good or service that they provide and a lack of viable substitute goods. Monopoly should be distinguished from monopsony, in which there is only one buyer of the product or service; it should also, strictly, be distinguished from the (similar) phenomenon of a cartel. In a monopoly a single firm is the sole provider of a product or service; in a cartel a centralized institution is set up to partially coordinate the actions of several independent providers (which is a form of oligopoly).
Only one single seller in the market. There is no competition. There are many buyers in the market.
