Writing Purposes (PIE)
Writing Purposes: PIE
When we write, we always have a purpose. A purpose is the reason we are writing.
One easy way to remember writing purposes is PIE:
- P = Persuade
- I = Inform
- E = Entertain
If you know your purpose, your writing will be clearer and stronger. It will help you choose the right words, details, and style.
Before you start writing, ask yourself, "Why am I writing this?" Your answer will often be persuade, inform, or entertain.
1. Persuade
To persuade means to try to get someone to think something, believe something, or do something.
Persuasive writing gives opinions and reasons. The writer wants the reader to agree.
You might persuade when you:
- write a letter asking for a class pet
- tell why recess should be longer
- explain why your favorite book is the best one to read
Words and clues that often show persuasive writing are:
- I think
- you should
- best
- because
- must
- important
Example of persuade:
Our school should plant more trees. Trees give shade on hot days. They also make the schoolyard look beautiful. More trees would make our playground a better place.
In this example, the writer gives an opinion and reasons. That means the purpose is persuade.
2. Inform
To inform means to teach the reader or give facts and information.
Informational writing explains a topic clearly. It helps the reader learn something new.
You might inform when you:
- write about how bees make honey
- explain the steps for planting seeds
- tell facts about a state, animal, or planet
Words and clues that often show informative writing are:
- first, next, then, finally
- facts
- for example
- explains
- is, are, has
Example of inform:
Frogs begin life as eggs. After the eggs hatch, they become tadpoles. Tadpoles live in water and slowly grow legs. Later, they become adult frogs.
This example teaches facts about frogs. The purpose is inform.
3. Entertain
To entertain means to amuse the reader or tell a story that is enjoyable to read.
Entertaining writing often includes characters, a setting, a problem, and events. It may be funny, exciting, or surprising.
You might entertain when you:
- write a short story
- create a funny comic scene
- tell about an imaginary adventure
Words and clues that often show entertaining writing are:
- story language
- characters
- dialogue
- action
- feelings
Example of entertain:
Maya opened the lunchbox and jumped back. Inside, her sandwich had two olive eyes and a carrot smile. "Do not eat me!" it squeaked. Maya blinked, then laughed.
This example tells a fun story. The purpose is entertain.
How to Tell the Difference
Sometimes writing can have more than one part, but usually one purpose is the main purpose.
Ask these questions:
- Is the writer trying to change my mind? That is persuade.
- Is the writer teaching me facts? That is inform.
- Is the writer telling a story for fun? That is entertain.
Think about these examples:
- A poster that says, "Read 20 minutes every night!" is mostly persuade.
- A page about sharks with facts and labels is mostly inform.
- A tale about a dog who drives a bus is mostly entertain.
Why Writing Purpose Matters
Knowing your purpose helps you make good writing choices.
- If you want to persuade, give strong reasons and examples.
- If you want to inform, include clear facts and explain carefully.
- If you want to entertain, make the writing interesting and fun to read.
Your purpose also helps you think about your audience. Your audience is the person or group who will read your writing.
For example:
- If you are writing to the principal, your persuasive writing should be polite and clear.
- If you are writing a report for classmates, your informative writing should be easy to understand.
- If you are writing a story for younger students, your entertaining writing should be fun and simple to follow.
