What is an "exponent" in terms of a speaker?

An exponent, in the context of a speaker, refers to someone who advocates or explains a particular idea or concept. This role involves actively promoting or supporting a viewpoint, often by providing clear explanations and arguments that make the idea more understandable to the audience. An exponent not only shares information but also often works to persuade others of its validity or importance.

In contrast to other roles, such as a listener or an interrogator, the exponent takes on an active position in communication. This means they engage with the audience in a way that encourages further understanding and engagement with the subject matter. Their function is critical in discussions where ideas need to be illuminated or defended.
