Rhetoric aims to study the techniques writers or speakers utilize to inform, persuade, or motivate particular audiences in specific situations. The five canons of rhetoric or phases of developing a persuasive speech were first codified in classical Rome: invention , arrangement , style , memory , and delivery. From Ancient Greece to the late 19th century, rhetoric played a central role in Western education in training orators, lawyers, counsellors, historians, statesmen, and poets. Scholars have debated the scope of rhetoric since ancient times. Although some have limited rhetoric to the specific realm of political discourse, many modern scholars liberate it to encompass every aspect of culture. Contemporary studies of rhetoric address a much more diverse range of domains than was the case in ancient times.

Rhetorical analysis is a form of criticism or close reading that employs the principles of rhetoric to examine the interactions between a text, an author, and an audience. It's also called rhetorical criticism or pragmatic criticism. Rhetorical analysis may be applied to virtually any text or image—a speech , an essay , an advertisement, a poem, a photograph, a web page, even a bumper sticker. When applied to a literary work, rhetorical analysis regards the work not as an aesthetic object but as an artistically structured instrument for communication.
