From this article I found out that Rhetoric has a whole history behind itself. In the beginning this word had only a strict meaning – art of the orator, public speaking. Later on via couple of centuries this word got a totally different definition and explanation, it became wider. Today rhetoric work starts event before the speech. For the orator very important to understand before the public speech what kind of group with what material status, ethnicity or culture you’re trying to persuade. Nowadays “Rhetoric” includes three main section such as: Claim, Support and Warrant. If the orator know how to use those three section he will be able to persuade any kind of people.
