Formal and Informal Writing

Welcome to the World of Formal and Informal Writing!

Have you ever noticed how you speak differently to your best friend than you do to a teacher or a doctor? In English, we call this register. Choosing the right "voice" for your writing is like picking the right outfit for an occasion. You wouldn’t wear your pajamas to a wedding, and you probably wouldn’t wear a tuxedo to go for a run!

In this chapter, we are going to learn how to switch between Formal and Informal styles so you can communicate perfectly in every situation.

1. The Basics: What is the Difference?

The main difference between formal and informal writing comes down to your Audience (who is reading it) and your Purpose (why you are writing it).

Informal Writing: The "Comfy Clothes" of English

Informal writing is the way we write when we are relaxed and know the person well. It is personal, chatty, and uses everyday language.

When to use it:
• Text messages to friends
• Postcards to family
• Personal diaries or journals
• Social media captions

Common Features:
• Contractions: Shortened words like don't, it's, or won't.
• Slang and Idioms: Phrases like "What’s up?" or "Piece of cake."
• Exclamation Marks: Used to show excitement ("Can't wait!").
• Personal Pronouns: Using "I", "me", and "you" a lot.

Formal Writing: The "Suit and Tie" of English

Formal writing is professional, polite, and serious. It avoids slang and follows the rules of grammar very strictly.

When to use it:
• School essays and reports
• Letters or emails to a Headteacher or a business
• Job applications
• Speeches for a formal event

Common Features:
• No Contractions: Always use the full words (e.g., do not instead of don't).
• Standard English: Using precise vocabulary (e.g., "I was annoyed" instead of "I was fuming").
• Objective Tone: It often focuses on facts rather than just feelings.
• Complex Sentences: Longer, more detailed sentences.

Quick Takeaway: Formal writing is for people you don't know well or people in authority. Informal writing is for people you are close to.

2. The "Vocabulary Swap"

One of the easiest ways to change your writing from informal to formal is by swapping "everyday" words for more "sophisticated" ones.

Don't worry if this seems tricky at first! You already know many of these words; it’s just about choosing the right one for the job.

Informal Word -> Formal Swap
• Get -> Receive
• Ask for -> Request
• Check -> Verify
• Tell -> Inform
• Help -> Assist
• So -> Therefore
• But -> However

Did you know? Using the word "However" instead of "But" at the start of a sentence is one of the quickest ways to make your school essays sound more professional!

3. Using the Correct Structure

The way you start and end your writing also changes depending on how formal you need to be. This is especially important for letters and emails.

Greetings (The Start)

Informal: "Hi Sam," or "Hey!"
Formal: "Dear Mr. Smith," or "To whom it may concern," (if you don't know their name).

Sign-offs (The End)

Informal: "See ya," "Cheers," or "Best,"
Formal: "Yours sincerely," (if you know their name) or "Yours faithfully," (if you started with "Dear Sir/Madam").

Memory Aid: Remember the "S" rule! If you start with a Specific name (like Mr. Jones), you end with Sincerely.

4. Common Mistakes to Avoid

Even the best writers sometimes slip up. Here are a few things to watch out for when you are trying to be formal:

1. Avoid "text speak": Never use u for you or lol in a formal essay.
2. Avoid "filler" words: Words like basically, like, and literally usually belong in informal speech, not formal writing.
3. Watch your punctuation: In formal writing, try not to use multiple exclamation marks (!!!). One full stop is usually much more powerful.
4. Passive Voice: In formal reports, we sometimes use the passive voice. For example, instead of saying "I broke the glass," a formal report might say "The glass was broken." This makes the writing sound more neutral.

5. Step-by-Step: How to Formalize a Sentence

Let's look at how we can transform a "chatty" sentence into a "formal" one step-by-step.

Step 1 (The Informal Start): "I think the school lunch is rubbish and we need to fix it."

Step 2 (Remove Slang): Change "rubbish" to "unsatisfactory" and "fix" to "improve".
"I think the school lunch is unsatisfactory and we need to improve it."

Step 3 (Be More Professional): Instead of "I think," try a more serious opening.
The Formal Result: "It is argued that the school's nutritional provisions are unsatisfactory; therefore, improvements are required."

Quick Review: To make a sentence formal, remove contractions, swap simple verbs for professional ones, and avoid "I think" where possible.

Summary Checklist

Before you finish your next writing task, ask yourself these three questions:

• Who is my audience? (Friend = Informal / Teacher = Formal)
• Are there any contractions? (Change can't to cannot for formal tasks)
• Is my vocabulary appropriate? (Use request instead of ask for formal tasks)

You've got this! Choosing the right style is a skill that gets easier the more you read and practice. Next time you see a poster or an email, try to guess if it is formal or informal!
