Analyzing Rhetoric and Author’s Purpose
Students analyze how an author uses rhetorical techniques to advance a purpose and influence an audience in a nonfiction text.

Identify the Author’s Purpose
An author’s purpose is the main result the author wants a text to achieve. Common purposes include informing, explaining, persuading, criticizing, and inspiring action, but a text may combine several purposes. To identify the central purpose, examine the main claim, the evidence the author emphasizes, and what the author asks readers to think, feel, or do. Do not rely only on the topic. Two authors may discuss the same topic for different reasons. For example, an article about a later school start time might explain research on teenage sleep, but its repeated claims that the district “must change its schedule” reveal a persuasive purpose. Statistics about sleep and academic performance advance that purpose by making the proposed change appear necessary and beneficial. A strong purpose statement names both the author’s goal and the main idea being advanced.
Define the Intended Audience
The intended audience is the group of readers the author most wants to reach or influence. Authors adapt their language, evidence, examples, and assumptions to that group. Look for direct forms of address, specialized vocabulary, references to shared concerns, and the place where the text appears. For example, a letter sent to a city council requesting protected bike lanes is aimed primarily at council members, even if other residents read it. The writer might discuss traffic budgets, public safety data, and local ordinances because council members can approve funding and policy changes. A social media post on the same issue might instead use a personal story and a brief slogan to reach local voters. Identifying the audience helps explain why an author chooses certain rhetorical strategies and why an argument may affect one group more strongly than another.
Recognize Rhetorical Appeals
Rhetorical appeals are methods authors use to make ideas convincing. Logos appeals to reason through facts, examples, statistics, and logical connections. Ethos builds trust by showing expertise, fairness, experience, or reliable sources. Pathos appeals to emotions and values through vivid details, personal stories, or emotionally charged language. Effective texts often combine all three. In a speech supporting water conservation, a scientist might cite reservoir data to use logos, explain her years of drought research to establish ethos, and describe families watching wells run dry to create pathos. These appeals do not automatically make an argument sound or ethical. A dramatic story may stir emotion without representing typical experiences, and a statistic may be misleading without context. Analysis should identify each appeal, cite the specific language or evidence that creates it, and explain how it may influence the intended audience.
Analyze Word Choice and Tone
Word choice, also called diction, shapes a text’s tone and guides the audience’s response. Tone is the author’s attitude toward the subject or audience, such as respectful, urgent, skeptical, hopeful, or angry. Pay attention to words with strong connotations, repeated phrases, comparisons, and changes in formality. For example, an author who calls a public transportation plan an “investment in the city’s future” creates a hopeful, forward-looking tone. Calling the same plan a “costly experiment” produces a skeptical tone. The phrases refer to the same proposal, but their connotations encourage different judgments. When analyzing diction, move beyond labeling the tone. Quote or identify important words, explain the ideas or feelings they suggest, and connect those effects to the author’s purpose. Also consider whether the tone suits the audience; insulting language may weaken an argument directed toward undecided readers.
Evaluate the Rhetoric’s Effectiveness
Evaluating rhetoric means judging how well an author’s choices advance the purpose for the intended audience. Effectiveness is not the same as agreeing with the author. Consider whether the claims are clear, the evidence is relevant and sufficient, the reasoning is logical, the tone fits the audience, and opposing views are addressed fairly. Also check whether emotional language clarifies the issue or distracts from weak evidence. For example, an editorial seeking limits on student phone use may effectively cite classroom research, acknowledge that phones help families communicate, and propose exceptions for emergencies. This combination could persuade parents and school leaders because it addresses both learning and safety concerns. By contrast, calling all phone users “careless addicts” may alienate students and weaken the editorial’s credibility. A complete evaluation cites specific rhetorical choices, explains their likely effects, and reaches a reasoned judgment about the text’s overall success.
