Author's Purpose & Tone

Introduction

Why This Matters: Purpose tells you what response an author wants from an audience; tone reveals the author's attitude through language. A text can supply facts while primarily trying to change behavior, and a narrator's voice is not automatically the real author's position.

What You Need to Know

Author's Purpose

Every text is written for a reason:

Most real texts have mixed purposes. Rank them instead of counting features. A park brochure may describe trails and report distances, but if its repeated invitations and registration link aim to increase visits, persuasion is primary and information is secondary. Ask: What does the author most want the intended audience to know, feel, believe, or do?

Purpose also depends on audience and venue. The same flood data could appear in a neutral city report, a fundraising letter, or a resident's memoir. Facts do not automatically make “inform” the primary purpose; examine the selection of facts, calls to action, structure, and desired response.

Tone

Tone is the author's attitude toward the subject—how they "feel" about it.

Point of view is grammatical position: first person (I/we), second person (you), or third person (he/she/they). Perspective is the outlook shaped by experience, knowledge, interests, or role. A first-person account can be accurate, and a prestigious third-person publication can still frame evidence selectively. Judge the particular claim and its evidence rather than trusting or rejecting a source solely because of POV.

In fiction, distinguish the narrator from the author. A first-person narrator reports only what that character notices and may misunderstand events. A third-person limited narrator follows one character's knowledge; a third-person omniscient narrator can reveal the thoughts of several characters. These choices shape what readers know, but they do not by themselves establish the author's attitude.

🧠 Memory Trick

PIE = Purpose

• Persuade
• Inform
• Entertain

For Tone: Ask "How would this sound if read aloud?"

Imagine the author's voice—are they excited? Worried? Neutral like a robot? Angry?

Identifying Author's Purpose

Clues for Each Purpose:

INFORM:

• Presents facts without opinion
• Uses neutral language
• Includes data, statistics, definitions
• No call to action
• Example: "The heart pumps approximately 2,000 gallons of blood daily."

PERSUADE:

• Uses emotional language
• Includes opinions presented as facts
• Has a call to action
• Uses words like "should," "must," "need to"
• Example: "We must increase nurse staffing ratios to save lives."

ENTERTAIN:

• Uses humor, suspense, or drama
• Focuses on engagement over facts
• Often tells a story
• Example: "The night shift was quiet—too quiet. Then Room 312's call light flickered on..."

Identifying Tone

Look for:

1. Word choice (diction): "Issue" vs. "crisis" vs. "disaster"
2. Sentence structure: Length and rhythm are clues; short sentences can be calm and long ones emotional. Weigh diction, context and the whole passage.
3. Punctuation: Exclamation marks = excitement/urgency
4. Figurative language: Metaphors, sarcasm, exaggeration

Perspective, Narrative Point of View, and Credibility

Do not collapse three different questions:

• Who speaks? First person (I/we), second person (you), or third person (she/he/they).
• What can that voice know? Use the short narration comparison above to check whose knowledge the passage reveals.
• What outlook shapes the account? A homeowner, renter, builder, and conservationist may describe the same development proposal from different perspectives.

Narrative voice is not automatically the author's own stance. An author may create an overconfident narrator whose mistaken interpretation is corrected by later events. Likewise, first person is not inherently unreliable, and an institutional source is not inherently correct. Evaluate a source claim by claim: relevant expertise, direct access to the information, evidence quality, incentives, currency, and corroboration all matter.

Example: A harbor business owner writes, “The new pier will revive our quiet waterfront,” while a marine biologist writes, “Construction may disturb the eelgrass nursery.” The grammatical POV may be first person in the first account and third person in the second, but the deeper contrast is perspective: expected commercial benefit versus ecological risk. A balanced synthesis would not decide credibility from job title alone; it would inspect each claim's evidence.

✏️ Worked Examples

Example 1: Identify Purpose

What we're looking for: Why did the author write this? To teach facts, to convince us of something, or to keep us entertained?

Passage A: "Vitamin D deficiency affects approximately 42% of American adults. Symptoms include fatigue, bone pain, and muscle weakness. The recommended daily intake is 600-800 IU for most adults."

Step 1 — Read the passage and notice what kind of language is being used. Three sentences, all facts: a statistic (42%), a list of symptoms, and a recommendation based on established intake guidelines. No emotional pull. No call to action.

Step 2 — Ask: Is there any attempt to make me feel something or DO something? Nope. The author is just handing over information. You could fact-check every sentence.

Step 3 — Identify signal words or patterns. No "you should," no "buy this," no story. Pure factual delivery.

Purpose: INFORM — Presents facts neutrally without trying to sell anything or entertain.

Passage B: "Don't let vitamin D deficiency drain your energy! Our new SuperD supplement delivers 2000 IU of pure vitamin D3. Order now and feel the difference within weeks!"

Step 1 — Read and notice the language immediately. "Don't let... drain your energy!" — that's emotional. Exclamation marks everywhere.

Step 2 — Ask: Is there a call to action? "Order now" — yes, that's the most obvious call to action possible.

Step 3 — Look for loaded/emotional language. "Drain your energy" (fear), "feel the difference" (promise), "weeks!" (urgency). The author wants you to BUY something.

Purpose: PERSUADE — Uses emotional language, makes promises, includes a direct call to action ("Order now").

TEAS Tip: Advertisements commonly persuade, while research reports commonly inform, but genre is only a clue. Confirm purpose from the audience, selected evidence, structure, and intended response.

Example 2: Identify Tone

What we're looking for: How does the author FEEL about the subject? What's their emotional attitude?

Passage: "Despite decades of research and billions in funding, we are no closer to a cure for Alzheimer's disease. The pharmaceutical industry continues to chase failed approaches while patients and families suffer. It's time for a fundamental change in strategy."

Step 1 — Read the passage and circle emotionally charged words.

• "Despite decades… billions in funding" → implies effort wasted
• "no closer" → frustration with lack of progress
• "failed approaches" → criticism of the industry
• "patients and families suffer" → appeals to pain
• "fundamental change" → urgent call to action

Step 2 — Ask: If I read this out loud, what emotion would I be projecting? Disappointment. Anger. Urgency. This person is NOT happy.

Step 3 — Choose the tone word that fits best. The author is pointing out failures and calling for change. That's critical — finding fault. Combined with the emotional weight, also frustrated.

Tone: Critical/Frustrated — Words like "despite," "no closer," "failed," and "suffer" all signal disappointment and criticism. The author is not presenting this neutrally.

Example 3: Combined Analysis — Purpose AND Tone Together

What we're looking for: Both WHY the author wrote this and HOW they feel about the subject.

Passage: "The new electronic health record system has reduced medication errors by 35% in our pilot program. Staff training took only two days, and nurse satisfaction scores increased. We recommend all healthcare facilities consider implementing similar systems."

Step 1 — Read and look for the action word. Last sentence: "We recommend all healthcare facilities consider implementing similar systems." That's a recommendation — the author is trying to get other facilities to adopt this system.

Step 2 — Identify the purpose. The passage backs up the recommendation with data (35% error reduction, fast training, nurse satisfaction). But the GOAL is to convince readers to act. That's persuasion — even though it uses facts to do it.

Step 3 — Now look at the tone — how is the author presenting all this? Everything is positive: errors down 35%, training was quick ("only two days"), nurses are happier. The author is clearly enthusiastic about this system.

Step 4 — Name the tone. Upbeat. Positive. Championing a solution. → Optimistic/Supportive

Purpose: PERSUADE — recommends action ("we recommend") Tone: Optimistic/Supportive — all evidence presented positively, cheering for this solution

Key insight: Notice that this passage uses facts to persuade. Not all persuasion is obvious or emotional. A recommendation may support a persuasive purpose, but weigh the whole passage and the response sought from the audience; an informative report can also mention recommendations.

💡 Pro Tips

• One passage can have multiple purposes: A textbook might inform AND persuade you that the topic matters
• Tone can shift: An article might start neutral and become urgent by the end
• Scientific writing is usually "to inform" with an objective tone
• Look for bias indicators: "Obviously," "clearly," "everyone knows" suggest persuasion, not neutral information

⚠️ Common Mistakes to Avoid

• Confusing topic with purpose: A passage ABOUT vaccines might inform, persuade, OR entertain depending on how it's written
• Missing subtle persuasion: Academic articles can persuade while appearing purely informative
• Confusing author's tone with your reaction: The passage might be "objective" even if the topic makes YOU feel emotional
• Overthinking tone: If it sounds like a textbook, it's probably "formal" or "objective"
