Author's purpose guide for teachers and students.


what is THE author’s purpose?

author's purpose

When discussing the author’s purpose, we refer to the ‘why’ behind their writing. What motivated the author to produce their work? What is their intent, and what do they hope to achieve?

The author’s purpose is the reason they decided to write about something in the first place.

There are many reasons a writer puts pen to paper. Our students must possess the necessary tools to identify these various reasons and intents.

Identifying the author’s purpose accurately is essential if the student is to evaluate a piece of writing effectively.


Depending on who you talk to or what you read when the question is raised about how many types of authors’ purposes there are, you’ll generally be quoted a number ranging from around 3 to about 7.

We have listed all seven below, but we will cover the five most common author’s purposes in detail in this article as they appear on most lists; the first three are found on every list, and the final two are found sporadically.

  • To Inform: The author aims to provide factual information to the reader.
  • To Persuade: The author aims to convince the reader to agree with a particular viewpoint or take a specific action.
  • To Entertain: The author aims to engage and amuse the reader through storytelling, humor, or other means.
  • To Describe: The author uses vivid language to paint a picture in the reader’s mind.
  • To Explain: The author aims to clarify or simplify a complex topic or concept.
  • To Argue: The author aims to present a reasoned case for or against a particular idea or position.
  • To Instruct: The author’s purpose is to provide step-by-step guidance or directions to the reader.

Whilst we are covering five, a good starting point for younger students is, to begin with, the central three purposes; to persuade, to inform, and to entertain. These can easily be remembered with the PIE acronym and should be the starting point on this topic.


The author’s purpose is their intent (or purpose) for writing something. To either persuade, inform or entertain an audience.

You will most commonly see these three aspects attributed as the author’s purpose; however, as mentioned previously, other elements, such as describing and explaining, are also commonly sighted.

Let’s get into it and see some author’s purpose examples.

author's purpose | authors purpose persuade 1 | The Author's Purpose for students and teachers |

Definition: This is a very common purpose of writing, particularly in nonfiction writing. When a text is written to persuade, it will aim to convince the reader of the merits of a particular point of view. With this type of writing, the author will attempt to persuade the reader to agree with this point of view and/or subsequently take a particular course of action. 

Examples: This purpose can be found in all kinds of writing. It can even be in fiction writing when the author has an agenda, consciously or unconsciously. However, it is most commonly the motivation behind essays, advertisements, and political writing, such as speech and propaganda.

Persuasion is commonly also found in…

  • A political speech urging voters to support a particular candidate by presenting arguments for their suitability for the position, their policies, and their record of achievements.
  • An advertisement for a new product that emphasizes its unique features and benefits over competing products, attempting to convince consumers to choose it over alternatives.
  • A letter to the editor of a newspaper expressing a strong opinion on a controversial issue and attempting to persuade others to adopt a similar position by presenting compelling evidence and arguments.

How to Identify: To identify when the author’s purpose is to persuade, students should ask themselves if they feel the writer is trying to get them to believe something or take a specific action. They should learn to identify the various tactics and strategies used in persuasive writing, such as repetition, various types of supporting evidence, hyperbole, attacking opposing viewpoints, forceful phrases, emotive imagery and photographs etc.

author's purpose | authors purpose inform | The Author's Purpose for students and teachers |

Definition: When an author aims to inform, they usually wish to enlighten their readership about a real-world topic. Often, they will do this by providing lots of facts. Informational texts impart information to the reader to educate them on a given topic. 

Examples: Many types of school books are written with the express purpose of informing the reader, such as encyclopedias, recipe books, newspapers and these informative texts…

  • A news article reporting on a recent event or development provides factual details about what happened, who was involved, and where and when it occurred.
  • A scientific journal article describes a research study’s findings, explaining the methodology, results, and implications for further study or practical application.
  • A travel guidebook that provides detailed information about a particular destination, including its history, culture, attractions, accommodation options, and practical advice for visitors.

How to Identify: In the process of informing the reader, the author will use facts, which is one surefire way to spot the intent to inform.

However, when the author’s purpose is persuasion, they will also likely provide the reader with some facts to convince them of the merits of their particular case. The main difference between the two ways facts are employed is that when the intention is to inform, facts are presented only to teach the reader. When the author aims to persuade, they commonly mask their opinions amid the facts.

Students must become adept at recognizing ‘hidden’ opinions through practice. Teach your students to beware of persuasion masquerading as information!

Definition: When an author’s chief purpose is to entertain the reader, they will endeavour to keep things as interesting as possible. Things happen in books that are written to entertain, whether in the form of an action-packed plot, inventive characterizations, or sharp dialogue.

author's purpose | authors purpose entertain | The Author's Purpose for students and teachers |

Examples: Not surprisingly, much fiction is written to entertain, especially genre fiction. For example, we find entertaining examples in science fiction, romance, and fantasy.

Here are some more entertaining texts to consider.

  • A novel that tells a compelling story engages the reader’s emotions and imagination through vivid characters, evocative settings, and unexpected twists and turns.
  • A comedy television script that uses humor and wit to amuse the audience, often by poking fun at everyday situations or societal norms.
  • A stand-up comedy routine that relies on the comedian’s storytelling ability and comedic timing to entertain the audience, often by commenting on current events or personal experiences.

How to Identify: When writers attempt to entertain or amuse the reader, they use various techniques to engage their attention. They may employ cliffhangers at the end of a chapter, for example. They may weave humour into their story or even have characters tell jokes. In the case of a thriller, an action-packed scene may follow an action-packed scene as the drama builds to a crescendo. Think of the melodrama of a soap opera here rather than the subtle touch of an arthouse masterpiece.



author's purpose | The Author's Purpose for students and teachers |

Definition: When writers write to explain, they want to tell the reader how to do something or reveal to them how something works. This type of writing is about communicating a method or a process.

Examples: Writing to explain can be found in instructions, step-by-step guides, procedural outlines, and recipes such as these…

  • A user manual explaining how to operate a piece of machinery or a technical device provides step-by-step instructions and diagrams to help users understand the process.
  • A textbook chapter that explains a complex scientific or mathematical concept breaks it into simpler components and provides examples and illustrations to aid comprehension.
  • A how-to guide that explains how to complete a specific task or achieve a particular outcome, such as cooking a recipe, gardening, or home repair. It provides a list of materials, step-by-step instructions, and tips to ensure success.

 How to Identify:  Often, this writing is organized into bulleted or numbered points. As it focuses on telling the reader how to do something, often lots of imperatives will be used within the writing. Diagrams and illustrations are often used to reinforce the text explanations too.

author's purpose | authors purpose describe | The Author's Purpose for students and teachers |

Definition: Writers often use words to describe something in more detail than conveyed in a photograph alone. After all, they say a picture paints a thousand words, and text can help get us beyond the one-dimensional appearance of things.

Examples: We can find lots of descriptive writing in obvious places like short stories, novels and other forms of fiction where the writer wishes to paint a picture in the reader’s imagination. We can also find lots of writing with the purpose of description in nonfiction too – in product descriptions, descriptive essays or these text types…

  • A travelogue that describes a particular place, highlighting its natural beauty, cultural attractions, and unique characteristics. The author uses sensory language to create a vivid mental picture in the reader’s mind.
  • A painting analysis that describes the colors, shapes, textures, and overall impression of a particular artwork. The author uses descriptive language to evoke the emotions and ideas conveyed by the painting.
  • A product review that describes the features, benefits, and drawbacks of a particular item. The author uses descriptive language to give the reader a clear sense of the product and whether it might suit their needs.

How to Identify: In the case of fiction writing which describes, the reader will notice the writer using lots of sensory details in the text. Our senses are how we perceive the world, and to describe their imaginary world, writers will draw heavily on language that appeals to these senses. In both fiction and nonfiction, readers will notice the writer will rely heavily on adjectives in their writing.

The Author’s Purpose Task 1. The Author’s Purpose Anchor Chart

Whether introducing the general idea of the author’s purpose or working on identifying the specifics of a single purpose, a pie author’s purpose anchor chart can be an excellent resource for students when working independently. Compiling the anchor chart collaboratively with the students can be an effective way for them to reconstruct and reinforce their learning.

The Author’s Purpose Task 2. Gather Real-Life Examples

Challenging students to identify and collect real-life examples of the various types of writing as homework can be a great way to get some hands-on practice. Encourage your students to gather various forms of text together indiscriminately. They then sift through them to categorize them appropriately according to their purpose. The students will soon begin to see that all writing has a purpose. You may also like to make a classroom display of the gathered texts to serve as examples.

The Author’s Purpose Task 3. DIY

One of the most effective ways for students to recognize the authorial intent behind a piece of writing is to gain experience producing writing for various purposes. Design writing tasks with this in mind. For example, if you are focused on writing to persuade, you could challenge the students to produce a script for a radio advertisement. If the focus is entertaining, you could ask the students to write a funny story.

The Author’s Purpose Task 4. Classroom Discussion

When teaching author’s purpose, organize the students into small discussion groups of, say, 4 to 5. Provide each group with copies of sample texts written for various purposes. Students should have some time to read through the texts by themselves. They then work to identify the author’s purpose, making notes as they go. Students can discuss their findings as a group.

Remember: the various purposes are not mutually exclusive; sometimes, a text has more than one purpose. It is possible to be both entertaining and informative, for example. It is essential students recognize this fact. A careful selection of texts can ensure the students can discover this for themselves.

In Summary

 Students need to understand that regardless of the text they are engaged with, every piece of writing has some purpose behind it. It’s important that they work towards recognizing the various features of different types of writing that reveal to the reader just what that purpose is.

Initially, the process of learning to identify the different types of writing and their purposes will require conscious focus on the part of the student. There should be plenty of opportunities created to allow for this necessary practice in the classroom.

However, this practice doesn’t have to be exclusively in the form of discrete lessons on the author’s purpose. Simply asking students what they think the author’s purpose is when reading any text in any context can be a great way to get the ‘reps’ in quickly and frequently.

Eventually, students will begin to recognize the author’s purpose quickly and unconsciously in the writing of others.

Ultimately, this improved comprehension of writing, in general, will benefit students in their own independent writing.
