Rhetoric refers to using language in speech or writing to influence or entertain people, as defined by the Oxford Advanced Learners Dictionary. There are three appeals of rhetoric: ethos which relies on the character or authority of the speaker, logos which uses reason-based arguments, and pathos which appeals to the emotions of the audience. When using rhetoric effectively, one must consider inventio (ideas and facts), dispositio (organization), elocutio (language), memoria (memorization), and pronuntiatio (delivery). An example is making a case for or against homework by convincing the audience through emotional and logical appeals while using an engaging speaking style.
