Author's purpose guide for teachers and students.



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

When we talk of the author’s purpose we are referring 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. It’s important that our students possess the necessary tools for identifying these various reasons and intents.

Being able to identify the author’s purpose accurately is absolutely essential if the student is to effectively evaluate a piece of writing.


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

A good starting point for students beginning to learn more about the different types of authors’ purpose is, to begin with, the main 3: to persuade, to inform, and to entertain. These can easily be remembered with the PIE acronym.

However, these 3 represent only an introduction. In the interests of covering the topic a little more comprehensively, we will define 5 different types of author’s purpose, look at some examples of each in use, and give a few pointers helpful in identifying them.

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 being the author’s purpose however other elements such as describing and explaining are commonly sighted as well.

We will explore the author’s purpose in much more detail throughout this article.

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 certain 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, whether consciously or unconsciously. However, it is most commonly the motivation behind essays, advertisements, and political writing such as speeches and propaganda.

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.

We have a complete guide to persuasive writing here if you would like to learn more.


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

Definition: When an author’s purpose is 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 are geared toward imparting information to the reader with the purpose of educating them on a given topic. 

Examples: Many types of school books are written with the express purpose of informing the reader. Added to textbooks, we also have encyclopedias, recipe books, and newspapers. 

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

However, when the author’s purpose is persuasion they will also be likely to provide the reader with some facts in an attempt to convince the reader of the merits of their particular case. The main difference between the two different ways facts are employed is that, when the intention is to inform, facts are presented only to teach the reader. When the author’s purpose is to persuade, they will 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!

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

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.

 Examples: Not surprisingly, a great deal of fiction is written with the aim of entertaining, especially genre fiction. For example, we find entertaining examples in science fiction, romance, and fantasy – to name but a few.

How to Identify: When a writer is attempting to entertain or amuse the reader they will use a variety of 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 art house 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 with the purpose of explaining can be found in instructions, step-by-step guides, procedural outlines, and recipes.

 How to Identify:  Often you will find this type of writing 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: Often writers will use words to describe something in more detail than be 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 or descriptive essays, for example.


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, an anchor chart can be a great 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 together real-life examples of the various types of writing as homework can be a great way for them 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 some experience in producing writing for various purposes themselves. 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 to entertain, you could ask the students to write a funny story etc.

The Author’s Purpose Task 4. Classroom Discussion

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 will have more than a single purpose. It is possible to be both entertaining and informative, for example. It is important students recognize this fact. Careful selection of texts can ensure the students get an opportunity to 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.

This practice doesn’t have to be exclusively in the form of discrete lessons on the author’s purpose, however. 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.
