Quora Answer: What do You Call a Person Who Studies & Masters Rhetoric?

The following is my answer to a Quora question: “What do you call a person who studies and masters rhetoric?” 

Rhetoric is the mastery of the art of putting forth a cogent, coherent argument, for or against a contention, with the intent of convincing or persuading someone or a group of people towards a specific position.  It includes the ability to engage in the ensuing dialogue to achieve that objection.  In English, the person who masters rhetoric is known as a rhetorician.  A rhetorician is known for his ability to speak eloquently.  However, the one who masters, and then teaches this art is actually called a rhetor, a term derived from Ancient Greece.
