A "representative" is a person chosen or elected to act on behalf of others. In a political context, representatives are often members of a legislative body, such as the U.S. Congress, where they make decisions and create laws that reflect the interests of their constituents. In a broader sense, a representative can also refer to someone who showcases or exemplifies a particular group, idea, or product. For example, a sales representative promotes a company's products to potential customers, acting as a link between the business and the public.
