Reading is good — doing is better. Practice Why Did the Author Write This? as an interactive lesson.

Definition

Author's purpose is the main reason a writer decided to write something. Almost every piece of writing is meant to do one of three things: to teach you facts (inform), to make you laugh or feel something (entertain), or to talk you into believing or doing something (persuade).

Remember the rule

PIE: Persuade · Inform · Entertain — every piece of writing fits one of these three slices!

Persuade: To try to talk the reader into agreeing with an idea or doing something.

Common mistakes

Thinking a story can only entertain — sometimes a story also teaches a lesson, but the main purpose is still usually to entertain.
Confusing inform and persuade — if the writing only shares facts with no opinion, it informs; if it tries to change your mind, it persuades.
Choosing the purpose based on the topic instead of the writing — a book about dogs could inform, entertain, OR persuade depending on how it is written.
Forgetting to look for clue words — words like 'you should,' 'always,' and 'never' often signal persuade; question-and-answer text often signals inform.
Saying the author wrote it 'because they wanted to' — that is not a purpose; you need to say inform, entertain, or persuade.

FAQs

Can a piece of writing have more than one purpose?

Yes! A book can be entertaining AND teach you facts. But usually one purpose is the MAIN one. Ask yourself: what is the biggest reason the author wrote this?

How do I figure out the author's purpose if I am not sure?

Ask three questions: Does it give me facts? (Inform.) Does it tell a fun or made-up story? (Entertain.) Does it try to change what I think or do? (Persuade.) Whichever fits best is the purpose.

Are nonfiction books always written to inform?

Almost always, yes — but some nonfiction books, like funny true-story memoirs, are also meant to entertain. Check if the main job is giving facts or making you enjoy reading.

What clue words help me spot persuade?

Look for words like 'should,' 'must,' 'best,' 'please,' 'you need to,' and phrases that give opinions like 'I believe' or 'It is important that.'

Do authors always tell us their purpose?

No — authors almost never say 'I am writing this to inform you.' You have to be a reading detective and use clues from the words, pictures, and type of writing.

Why does knowing the author's purpose matter?

It helps you read smarter! When you know the purpose, you know whether to look for facts, enjoy the story, or think carefully about whether you agree with the author.
