15 What is rhetorical analysis?

Simply defined, rhetoric is the art or method of communicating effectively to an audience, usually with the intention to persuade; thus, rhetorical analysis means analyzing how effectively a writer or speaker communicates her message or argument to the audience.

The ancient Greeks, namely Aristotle, developed rhetoric into an art form, which explains why much of the terminology that we use for rhetoric comes from Greek.  The three major parts of effective communication, also called the Rhetorical Triangle, are ethos, pathos, and logos, and they provide the foundation for a solid argument. As a reader and a listener, you must be able to recognize how writers and speakers depend upon these three rhetorical elements in their efforts to communicate. As a communicator yourself, you will benefit from the ability to see how others rely upon ethos, pathos, and logos so that you can apply what you learn from your observations to your own speaking and writing.

Rhetorical analysis can evaluate and analyze any type of communicator, whether that be a speaker, an artist, an advertiser, or a writer, but to simplify the language in this chapter, the term “writer” will represent the role of the communicator.
