Explanation:

Rhetoric (/ˈrɛtərɪk/)[note 1] is the art of persuasion, which along with grammar and logic (or dialectic – see Martianus Capella), is one of the three ancient arts of discourse. Rhetoric aims to study the techniques writers or speakers utilize to inform, persuade, or motivate particular audiences in specific situations.[5] Aristotle defines rhetoric as "the faculty of observing in any given case the available means of persuasion" and since mastery of the art was necessary for victory in a case at law; or for passage of proposals in the assembly; or for fame as a speaker in civic ceremonies; he calls it "a combination of the science of logic and of the ethical branch of politics".[6] Rhetoric typically provides heuristics for understanding, discovering, and developing arguments for particular situations, such as Aristotle's three persuasive audience appeals: logos, pathos, and ethos. The five canons of rhetoric or phases of developing a persuasive speech were first codified in classical Rome: invention, arrangement, style, memory, and delivery.
