Author's Purpose: The 3 Main Types With Examples
Every piece of writing exists because the author wanted something. They wanted to change your mind, teach you something, or make you feel something. Author's purpose is the reason behind the text — the driving intention that shapes every word choice, structural decision, and rhetorical move. Understanding purpose is the difference between reading passively and reading like a writer.
The PIE Framework: Persuade, Inform, Entertain
The most widely taught framework for author's purpose uses the acronym PIE. It is simple, but it captures the three fundamental reasons any text exists. Most writing leans primarily toward one purpose, though skilled writers often blend all three.
Persuade
The author wants to convince the reader to adopt a belief, take action, or change their mind.
Common forms: Editorials, opinion essays, political speeches, advertisements, manifestos.
How to spot it: Strong claims, emotional appeals, calls to action, rhetorical questions, selective evidence.
Example: Thomas Paine's Common Sense (1776) — Paine wrote to convince American colonists that independence from Britain was not only justified but inevitable. Every sentence is engineered to move the reader from hesitation to certainty.
Inform
The author wants to teach the reader something, present facts, or explain a process.
Common forms: Textbooks, news articles, encyclopedia entries, how-to guides, scientific papers.
How to spot it: Neutral tone, factual language, data and statistics, structured explanations, absence of opinion.
Example: Charles Darwin's On the Origin of Species (1859) — Darwin's purpose is to present evidence for natural selection. The prose is methodical, layered with observation and data. He informs first; persuasion is a byproduct of the evidence itself.
Entertain
The author wants to engage, amuse, move, or captivate the reader through storytelling, humor, or artistry.
Common forms: Novels, short stories, poetry, screenplays, comedy, creative nonfiction.
How to spot it: Vivid imagery, narrative tension, character development, humor, emotional resonance, figurative language.
Example: J.R.R. Tolkien's The Lord of the Rings (1954) — Tolkien's primary purpose is to immerse readers in a secondary world so complete that it feels real. The entertainment comes from narrative pull, world-building, and the reader's desire to know what happens next.
Beyond PIE: Expanded Purposes
PIE is a useful starting point, but real writing is rarely so clean. Many texts exist to express, describe, or explain — purposes that overlap with PIE but deserve their own attention. Recognizing these helps you read more precisely and write with sharper intention.
Express
The author writes to process or share personal feelings, experiences, or reflections. The audience may be secondary to the act of writing itself.
Example: Sylvia Plath's journals, confessional poetry, personal essays. Plath's The Bell Jar expresses the interior experience of depression with such precision that the reader feels it viscerally.
Describe
The author writes to create a sensory picture — to make the reader see, hear, smell, or feel a place, person, or moment.
Example: Annie Dillard's Pilgrim at Tinker Creek — Dillard describes the natural world with such intensity that a creek becomes a cathedral. The purpose is not to inform about biology but to render perception itself.
Explain
The author breaks down a complex idea, process, or system so the reader can understand it. Closely related to informing, but focused on clarity over completeness.
Example: Stephen Hawking's A Brief History of Time — Hawking explains cosmology to non-specialists. Every analogy, every simplified equation, serves the purpose of making the incomprehensible graspable.
How to Identify Author's Purpose
Look at the genre and format
Genre is the first clue. A newspaper article exists to inform. A political pamphlet exists to persuade. A novel exists to entertain. This is not always true — some novels persuade, some journalism entertains — but genre sets the default expectation. Start there and adjust as you read.
Examine the language and tone
Persuasive writing uses emotionally charged words, rhetorical questions, and direct address. Informative writing uses neutral, precise language and avoids personal opinion. Entertaining writing uses vivid imagery, narrative tension, and figurative language. The diction tells you what the author wants from you.
Ask what the author wants you to do after reading
This is the sharpest test. If the author wants you to act or believe differently, the purpose is persuasion. If they want you to know something you didn't before, the purpose is information. If they want you to feel something — moved, amused, unsettled, transported — the purpose is entertainment. The intended effect reveals the purpose.
Notice when purposes overlap
The best writing rarely has a single purpose. George Orwell's 1984 entertains through narrative suspense, informs about the mechanisms of totalitarianism, and persuades the reader that political complacency is dangerous. Harper Lee's To Kill a Mockingbird entertains through Scout's voice while persuading the reader about racial injustice. Purpose is a spectrum, not a box.
How Understanding Purpose Improves Your Writing
Knowing your purpose before you write changes everything. It determines your structure, your tone, your level of detail, and your relationship with the reader. A writer who sits down without knowing their purpose drifts. A writer who knows their purpose makes every sentence serve it.
If your purpose is to persuade, you need strong evidence, emotional appeals, and a clear call to action. If your purpose is to inform, you need clarity, structure, and restraint — no editorializing. If your purpose is to entertain, you need narrative tension, voice, and the ability to make the reader care about what happens next. Purpose is not a constraint. It is a compass.
Exercises for Writers
Write the same topic three ways
Choose a single topic — a thunderstorm, a childhood memory, a city street. Write about it three times: once to inform the reader about what happened, once to persuade the reader that it matters, and once to entertain the reader with the experience. Notice how your word choices, sentence structures, and details shift with each version. The topic stays the same; the purpose changes everything else.
Reverse-engineer a favorite text
Take a passage you admire — a novel opening, an essay paragraph, a speech — and identify the author's primary and secondary purposes. Then identify the specific techniques they use to achieve those purposes. What words did they choose? What did they leave out? How does the structure serve the intention? Reading for purpose trains you to write with purpose.
State your purpose in one sentence before drafting
Before you start any piece of writing, write down a single sentence that answers: "I want the reader to ___." Fill in the blank. If you can't, you don't yet know what you're writing. This exercise takes ten seconds and saves hours of revision.
