Rhetorical Devices - ACT Reading

SECTION 1

Historical Context & Motivation

Long before standardized tests existed, people recognized that certain patterns of language could move audiences to action, shift opinions, and make ideas unforgettable. The formal study of these patterns—known as rhetorical devices—stretches back more than two thousand years to ancient Greece and Rome. Understanding how authors deploy these techniques is essential on the ACT Reading section, where Craft & Structure questions ask you to analyze why an author chooses specific words, phrases, and structural patterns to achieve a particular effect on the reader.

~400 BCE • Greek Roots of Rhetoric

Aristotle wrote Rhetoric, identifying three modes of persuasion—logos, pathos, and ethos—that remain foundational to how we analyze persuasive writing today.

~80 BCE • Roman Oratory Traditions

Cicero and later Quintilian cataloged dozens of rhetorical figures—like antithesis, anaphora, and chiasmus—used by public speakers in the Roman Senate and courts of law.

1776 • Rhetoric in American History

The Declaration of Independence used parallelism, repetition, and appeals to shared values to galvanize a revolution—demonstrating rhetoric's power beyond the classroom.

1963 • "I Have a Dream"

Dr. Martin Luther King Jr.'s famous speech layered anaphora, metaphor, and allusion so masterfully that it became a model text for studying rhetorical devices in schools worldwide.

Present • Rhetoric on the ACT

The ACT Reading test regularly asks students to identify the purpose and effect of rhetorical devices across literary narrative, social science, humanities, and natural science passages.

The central question this lesson addresses is straightforward but important: How do you recognize rhetorical devices in a passage, and how do you explain their effect on meaning and tone? Once you can answer that question reliably, you will find Craft & Structure questions on the ACT far more approachable.

SECTION 2

Core Principles & Definitions

A rhetorical device is any deliberate technique an author uses to persuade, emphasize, clarify, or create an emotional response in the reader. These devices fall into several broad categories, but on the ACT you should focus on recognizing the device and explaining what effect it has on the passage's meaning or tone. The five foundational principles below will guide your analysis.

Repetition Creates Emphasis

When authors repeat words, phrases, or grammatical structures (anaphora, parallelism), they signal that an idea is central to their argument and worth the reader's focused attention.

Figurative Language Builds Imagery

Metaphors, similes, personification, and hyperbole translate abstract ideas into vivid pictures, making complex arguments feel concrete and relatable to the audience.

Appeals Target Different Faculties

Logos appeals to logic, pathos to emotion, and ethos to credibility. Authors often blend all three, but ACT questions may ask which appeal dominates a particular passage or paragraph.

Tone Reflects the Author's Attitude

Devices like irony, understatement, and rhetorical questions shape tone—the author's attitude toward the subject. Identifying tone is often the bridge between recognizing a device and understanding its purpose.

Context Determines Effect

The same device can serve different purposes depending on context. A metaphor in a science article clarifies; a metaphor in a eulogy comforts. Always ask, 'What is the author trying to accomplish here?'

✦

KEY TAKEAWAY

Think of rhetorical devices like a musician's effects pedals. A guitarist can play the same notes, but adding reverb, distortion, or delay transforms the sound and emotional impact. Similarly, an author can present the same idea, but wrapping it in a metaphor, amplifying it with repetition, or sharpening it with antithesis completely changes how the reader experiences that idea. On the ACT, your job is to name the 'effect pedal' and explain what it does to the passage's meaning or tone.

SECTION 3

Visual Explanation — The Rhetorical Device Family Tree

This family tree organizes the major categories of rhetorical devices you will encounter on the ACT. The three main branches—figurative language, sound and repetition, and persuasive appeals—cover the devices tested most frequently. The bottom box highlights the three-step process for answering Craft & Structure questions.

As you can see in the diagram, the three main branches divide rhetorical devices by their primary function. Figurative language devices create imagery or make abstract ideas concrete. Sound and repetition devices add rhythm, emphasis, or memorability to prose. Persuasive appeals target the reader's logic, emotions, or trust in the author. On the ACT, most Craft & Structure questions will ask you to identify a device from one of these branches and then explain what the author achieves by using it. Keep in mind that a single sentence can employ devices from more than one branch simultaneously—for example, a writer might use a metaphor (figurative language) arranged in parallel structure (sound and repetition) to make an emotional appeal (pathos).

SECTION 4

How Rhetorical Devices Work — The Mechanism of Persuasion

Understanding rhetorical devices is not just about memorizing names; it's about understanding the mechanism through which each device operates. Every device works by creating a gap between ordinary language and the language the author actually uses. That gap—the difference between what you expected and what you got—is where meaning and emotional impact live. Let's explore this mechanism through the Aristotelian framework and the specific effects each device category produces.

The Aristotelian Appeals — Logos, Pathos, and Ethos

Aristotle argued that all persuasion rests on three pillars. Logos is an appeal to reason: the author uses evidence, facts, statistics, and logical reasoning to convince you. When a science passage on the ACT presents data and draws a conclusion, that's logos at work. Pathos is an appeal to emotion: the author uses vivid language, personal stories, or emotionally charged words to make you feel something—sympathy, outrage, hope. Ethos is an appeal to the author's credibility or moral character: references to expertise, shared values, or respected authorities build the reader's trust.

How Figurative Language Creates Meaning

Figurative language works by asking the reader to make a mental leap. A metaphor states that one thing is another ('Time is money'), forcing you to map the qualities of the second concept onto the first. A simile does the same thing but signals the comparison with 'like' or 'as' ('Her voice was like velvet'). Personification grants human qualities to non-human things ('The wind whispered'), which makes abstract forces feel relatable. Hyperbole deliberately exaggerates ('I've told you a million times') to emphasize intensity, while understatement deliberately minimizes ('It's just a scratch' when referring to a deep wound) to create ironic contrast.

How Repetition and Structure Create Rhythm

Anaphora—repeating the same word or phrase at the beginning of successive clauses—hammers a point home and builds emotional momentum. Consider King's 'I have a dream...' repeated across eight consecutive sentences; each repetition increases the power and urgency of the vision. Parallelism uses matching grammatical structures to convey equal importance ('government of the people, by the people, for the people'). Antithesis places contrasting ideas in parallel structure ('It was the best of times, it was the worst of times'), sharpening the reader's sense of opposition. Chiasmus reverses the order of elements in two parallel phrases ('Ask not what your country can do for you—ask what you can do for your country'), creating a memorable mirror effect.

This diagram shows how the three categories of rhetorical devices produce different effects—clarity and connection, emphasis and unity, and persuasion and trust—that combine to shape the reader's total experience. The dashed box at the bottom shows a typical ACT question stem you might encounter.

SECTION 5

Detailed Breakdown — Device-by-Device Classification

Now that you understand the three major categories, let's dig into the individual devices you are most likely to encounter on the ACT. The table below provides each device's name, a clear definition, an example, and the effect it creates. Use this as a reference guide when studying.

Device	Definition	Example	Effect on Reader
Metaphor	A direct comparison stating one thing is another	"The classroom was a zoo."	Creates vivid imagery; makes abstract ideas tangible
Simile	A comparison using "like" or "as"	"Her smile was like sunshine."	Clarifies unfamiliar concepts through familiar comparisons
Personification	Giving human qualities to non-human things	"The shadows crept across the lawn."	Makes descriptions more relatable and emotionally engaging
Hyperbole	Deliberate exaggeration for emphasis	"I could eat a horse."	Emphasizes intensity; can add humor or urgency
Understatement	Deliberately presenting something as less significant than it is	"The Pacific Ocean is a bit damp."	Creates irony; draws attention by surprising the reader
Anaphora	Repeating a word or phrase at the start of successive clauses	"We shall fight on the beaches, we shall fight on the landing grounds..."	Builds emotional intensity and rhythmic momentum
Parallelism	Using the same grammatical structure in related phrases	"To err is human; to forgive, divine."	Signals equality of ideas; creates pleasing rhythm
Antithesis	Juxtaposing contrasting ideas in parallel structure	"One small step for man, one giant leap for mankind."	Sharpens contrasts; highlights the significance of differences
Rhetorical Question	A question asked for effect, not expecting an answer	"If not now, when?"	Engages reader; implies that the answer is obvious
Allusion	A brief reference to a well-known person, event, or work	"He had a Midas touch with investments."	Adds layers of meaning by invoking shared cultural knowledge
Irony	A contrast between expectation and reality or between literal and intended meaning	A fire station burns down.	Creates surprise; provokes deeper thinking about contradictions

Common rhetorical devices tested on the ACT Reading section

💡

ACT STRATEGY TIP

You do not need to memorize the formal names of every device for the ACT. The test is more likely to describe a technique in the answer choices (e.g., 'the author uses an extended comparison' instead of 'the author uses a metaphor'). Focus on recognizing what the author is doing and why rather than worrying about terminology alone.

SECTION 6

Worked Example — Analyzing a Passage Excerpt

Let's walk through a realistic ACT-style passage excerpt and question, applying the three-step process from our diagram: identify the device, determine the author's purpose, and explain the effect on the reader.

📝

PASSAGE EXCERPT

"The old house sat at the edge of town like a forgotten sentinel, its windows staring blankly at passersby. Season after season, storm after storm, it endured—not because it was strong, but because no one cared enough to tear it down. To the children of Maple Street, it was a castle; to their parents, an eyesore; to the mayor, a problem best ignored."

Question: The author's description of the house in this paragraph primarily serves to: A) provide factual information about the building's construction. B) use figurative language and parallel structure to convey the house's symbolic role in the community. C) argue that the house should be preserved as a historical landmark. D) entertain the reader with humorous exaggeration.

Solving an ACT Craft & Structure Question

1
Step 1 — Identify the Devices

Read the excerpt closely. The phrase 'like a forgotten sentinel' is a simile comparing the house to a guard. 'Its windows staring blankly' is personification, giving the house human-like eyes. 'Season after season, storm after storm' is anaphora/repetition. The final sentence—'To the children... a castle; to their parents... an eyesore; to the mayor... a problem'—is parallelism with three parallel clauses.

Devices found: simile, personification, anaphora, parallelism
2
Step 2 — Determine the Author's Purpose

Ask yourself: why use these devices instead of straightforward description? The simile and personification make the house feel alive and watchful, suggesting it has symbolic weight beyond being a mere building. The parallelism in the final sentence presents three different perspectives on the house, showing that the house means different things to different people. The author's purpose is to establish the house as a symbol of the community's values and divisions.

Purpose: to show the house's symbolic role through figurative and structural devices
3
Step 3 — Match to the Best Answer

Now evaluate the answer choices. Choice A is wrong because the passage doesn't describe construction facts. Choice C is wrong because the author doesn't argue for preservation. Choice D is wrong because the tone is reflective, not humorous. Choice B correctly identifies that the author uses figurative language and parallel structure to convey the house's symbolic role.

Correct Answer: B

✦

KEY TAKEAWAY

When approaching Craft & Structure questions, treat each passage like a director's cut of a movie. Every 'camera angle' (device) was chosen on purpose. Your job isn't just to spot the special effect—it's to explain why the director used it in that specific scene. If you can articulate the connection between the device and the author's purpose, you'll consistently choose the right answer.

SECTION 7

Strengths & Limitations of Common Devices

Not all rhetorical devices are equally effective in every situation. Understanding each device's strengths and limitations will help you evaluate why an author chose one technique over another—a skill directly tested on the ACT. The table below compares the most commonly tested devices.

Device	Strengths	Limitations / When It Falls Flat
Metaphor	Creates powerful imagery; makes complex ideas accessible; can carry thematic weight across an entire passage	If the comparison is clichéd ('life is a journey'), it loses impact; extended metaphors can confuse if the comparison breaks down
Anaphora	Builds emotional momentum; creates rhythmic emphasis; makes key ideas memorable	Overuse becomes monotonous; works best in persuasive or narrative contexts, less effective in analytical writing
Rhetorical Question	Engages the reader directly; implies the answer is self-evident; effective for building an argument	If the answer isn't actually obvious, the device can seem manipulative or unclear
Irony	Reveals deeper truths; adds sophistication and wit; engages critical thinking	Can be misread as literal statement; requires shared understanding between author and reader
Allusion	Adds depth efficiently; connects the text to broader cultural knowledge; enriches meaning with minimal words	If the reader doesn't recognize the reference, the allusion fails; can seem elitist or exclusionary

Comparison of rhetorical device strengths and limitations

✦

KEY TAKEAWAY

On the ACT, you won't be asked whether a device is 'good' or 'bad.' Instead, you'll be asked what it accomplishes in context. Think about the strengths column: the correct answer will almost always describe a strength that aligns with the author's purpose. If an answer choice describes a limitation—like 'confuses the reader'—it's almost certainly wrong, because ACT passages are well-crafted texts where devices are used effectively.

SECTION 8

Connection to Advanced Analysis — Beyond Identification

Identifying a rhetorical device is only the first level of analysis. As you become a stronger reader—and as you encounter harder ACT passages—you'll need to move beyond naming devices to analyzing how they interact with one another and how they serve the passage's larger argument, theme, or structure. This is the bridge between ACT-level analysis and the kind of close reading you'll do in college-level English courses.

Skill Level	ACT-Level Analysis	Advanced / College-Level Analysis
Identification	"The author uses a metaphor comparing the economy to a machine."	"The machine metaphor reflects a mechanistic worldview that privileges efficiency over human welfare."
Purpose	"The metaphor helps the reader visualize how the economy functions."	"The metaphor naturalizes the idea that economic systems are predictable, obscuring the role of human choice."
Interaction	"The metaphor and the parallel structure both emphasize the economy's complexity."	"The extended metaphor is reinforced by parallelism that mimics the repetitive motion of gears, creating a sonic echo of the metaphor's content."
Evaluation	"The author's use of figurative language makes the argument more persuasive."	"The persuasiveness of the metaphor depends on the reader's willingness to accept its implicit analogy, which some economists would dispute."

Progression from ACT-level to college-level rhetorical analysis

For the ACT, you need to master the first two columns: identification and purpose. However, paying attention to how devices interact (column three) will give you an edge on the hardest questions. These questions often ask about the cumulative effect of several techniques used together—for example, 'The author's use of vivid imagery and parallel sentence structure in the third paragraph primarily serves to...' If you can see how devices layer on top of each other, you'll handle these questions with confidence.

ℹ

LOOKING AHEAD

In college-level composition and literature courses, rhetorical analysis becomes even more nuanced. You'll study how rhetorical devices reflect cultural contexts, power dynamics, and philosophical assumptions. The skills you build now—identifying devices, articulating purpose, and connecting technique to meaning—are the foundation for that deeper analysis.

SECTION 9

Practice Problems

Question 1: CONCEPTUAL

The following passage is from a memoir about growing up in a small town. "Our town was a sleeping giant, stretched out along the river, barely stirring even on the busiest of market days. The church steeple watched over us like a patient grandmother, and the cobblestone streets whispered stories of generations past." The author's use of personification in this passage primarily serves to:

A. emphasize the town's sense of history and quiet, living presence.
B. suggest that the town is literally alive and capable of human action.
C. create a tone of fear and unease about the town's atmosphere.
D. demonstrate that the narrator dislikes the town's lack of activity.

Show answer

The correct answer is A. The personification of the town as a "sleeping giant," the steeple as a "patient grandmother," and the streets that "whispered stories" all work together to convey a sense of warmth, history, and quiet vitality. Choice B is incorrect because personification is a figurative device, not a literal claim that the town is alive. Choice C is incorrect because the images used—a grandmother, whispering stories—evoke comfort and familiarity, not fear or unease. Choice D is incorrect because the tone of the passage is affectionate and nostalgic, not critical or resentful of the town's pace.

Question 2: BASIC

The following passage is from an essay about the importance of public libraries. "Libraries are not warehouses of dusty books. They are not relics of a bygone era. They are not luxuries we can afford to lose. Libraries are the beating hearts of their communities, pumping knowledge, opportunity, and hope into every neighborhood they serve." The rhetorical effect of the repeated sentence structure beginning with "They are not" is best described as:

A. building a list of criticisms the author agrees with before offering a rebuttal.
B. dismissing common misconceptions in order to strengthen the author's positive characterization of libraries.
C. showing the author's uncertainty about the future role of libraries in society.
D. providing factual evidence that libraries are used more today than in the past.

Show answer

The correct answer is B. The author uses anaphora—the repetition of "They are not"—to systematically reject negative perceptions of libraries before introducing a powerful metaphor that celebrates their importance. This structure makes the final positive claim feel more emphatic by contrast. Choice A is incorrect because the author clearly disagrees with each of the characterizations listed; these are misconceptions being refuted, not criticisms the author endorses. Choice C is incorrect because the author's tone is assertive and confident, not uncertain. Choice D is incorrect because the passage does not offer any factual data or statistics; instead, it relies on figurative language and rhetorical repetition.

Question 3: INTERMEDIATE

The following passage is from a speech delivered at a graduation ceremony. "You have spent four years memorizing formulas, analyzing literature, and debating history. You have pulled all-nighters before exams, celebrated hard-won victories on the field, and comforted friends through disappointments. But none of that—not the grades, not the trophies, not the late-night study sessions—matters as much as the single question you must now answer: What kind of person will you choose to be?" The speaker's use of specific, concrete details in the first two sentences most likely serves to:

A. remind the audience of their shared experiences so that the concluding question carries greater emotional weight.
B. argue that academic achievement is the most important measure of a student's success.
C. suggest that the audience has wasted their time on trivial pursuits during high school.
D. establish the speaker's credibility by showing familiarity with the students' daily routines.

Show answer

The correct answer is A. By cataloguing familiar, relatable experiences—studying, competing, supporting friends—the speaker creates a sense of shared identity with the audience. This accumulation of detail makes the pivot to the final question more powerful because it reframes all those experiences as secondary to a deeper moral challenge. Choice B is incorrect because the passage explicitly states that grades and trophies do not matter as much as character, directly undermining the idea that academics are paramount. Choice C is incorrect because the tone is respectful and celebratory, not dismissive; the speaker acknowledges these experiences as meaningful, even while subordinating them to a larger point. Choice D is incorrect because the primary rhetorical purpose is emotional connection and setup for the climactic question, not establishing the speaker's personal authority or expertise.

Question 4: APPLIED

The following passage is from an article about urban development. "The developers promised progress: gleaming towers of glass and steel rising where crumbling row houses once stood. They promised prosperity: new shops, new restaurants, new jobs flooding the neighborhood. They promised community: parks and plazas where families would gather on warm evenings. What they delivered was something else entirely. The towers rose, yes, but they cast long shadows over the people who could no longer afford to live in their shade." Which of the following best describes how the final two sentences function in relation to the rest of the passage?

A. They introduce a new argument that is unrelated to the developers' promises.
B. They use a shift in tone and an extended metaphor to undercut the optimistic rhetoric established earlier in the passage.
C. They provide statistical evidence that contradicts the developers' claims about economic growth.
D. They offer a balanced perspective by acknowledging both the benefits and drawbacks of the development.

Show answer

The correct answer is B. The first portion of the passage uses parallel structure and hopeful language ("promised progress," "promised prosperity," "promised community") to build an optimistic vision. The final two sentences abruptly shift to a critical tone, and the metaphor of towers casting "long shadows" over displaced residents transforms the earlier imagery of progress into one of harm. Choice A is incorrect because the final sentences directly respond to the promises outlined earlier, making them closely connected, not unrelated. Choice C is incorrect because the passage never provides statistics or data; it relies entirely on figurative language and rhetorical contrast. Choice D is incorrect because the final sentences do not acknowledge benefits in a balanced way—the concession "The towers rose, yes" is immediately followed by a critique, making the overall effect one of disapproval rather than balanced assessment.

Question 5: CRITICAL THINKING

The following passage is from a literary essay about the American landscape. "We have always told ourselves a particular story about the land: that it is vast, that it is generous, that it forgives. The prairie forgives the plow. The forest forgives the saw. The river forgives the dam. This is the story we tell because the alternative—that the land remembers every wound, that it keeps a meticulous accounting of what has been taken—is too terrible to live with. And so we choose the comfortable fiction, wrapping ourselves in it the way a child pulls a blanket over her head to hide from the dark. The dark, of course, does not go away." Taken as a whole, the author's use of rhetorical devices in this passage—including personification, parallel structure, analogy, and irony—most effectively works to:

A. celebrate the resilience of the American landscape and its capacity for renewal despite human interference.
B. expose the self-deception underlying a cultural narrative about the natural world and suggest that the consequences of environmental harm persist regardless of what people choose to believe.
C. argue that Americans should return to an earlier, pre-industrial relationship with the natural landscape.
D. compare two equally valid perspectives on the relationship between humans and the environment and leave the reader to choose between them.

Show answer

The correct answer is B. The passage systematically constructs a comforting national myth through personification (the land "forgives") and parallel structure ("The prairie forgives... The forest forgives... The river forgives") only to dismantle it. The author calls this belief a "comfortable fiction" and uses the analogy of a child hiding under a blanket to characterize it as naive self-deception, while the final ironic sentence—"The dark, of course, does not go away"—makes clear that ignoring environmental consequences does not eliminate them. Choice A is incorrect because the passage explicitly argues that the idea of the land's forgiveness is a fiction, not something to celebrate. Choice C is incorrect because the author critiques a cultural narrative but does not propose a return to a specific historical way of life; the argument is about self-awareness, not a particular policy. Choice D is incorrect because the author does not present both perspectives as equally valid—the passage clearly favors the view that the land "remembers every wound" and characterizes the opposing belief as a childish illusion.

SUMMARY

Lesson Summary — Rhetorical Devices on the ACT

Summary

Rhetorical devices are deliberate techniques authors use to persuade, emphasize, clarify, or evoke emotion. They fall into three main categories: figurative language (metaphor, simile, personification, hyperbole, understatement, irony), which creates vivid imagery and makes abstract ideas concrete; sound and repetition (anaphora, parallelism, antithesis, chiasmus, alliteration), which builds rhythm, emphasis, and memorability; and persuasive appeals (logos for logic, pathos for emotion, ethos for credibility), which target different faculties in the reader.

On the ACT Reading test, Craft & Structure questions ask you to follow a three-step process: (1) identify the device, (2) determine the author's purpose, and (3) explain the effect on the reader. Remember that context determines effect—the same device can serve different purposes in different passages. Always ask yourself, 'What is the author trying to accomplish here?' and connect the technique to the passage's overall argument, tone, or theme. Mastering rhetorical device analysis will not only boost your ACT score but also prepare you for the close-reading skills demanded in college-level coursework.
