Why is it important? 🧐

In IELTS Writing Task 1 (General Training), using the correct tone is essential, as it reflects your understanding of the task type and ensures your response is appropriate for the audience. Whether you’re writing to a friend, a colleague, or a formal institution, the formality of your tone directly impacts your Task Achievement and Lexical Resource.

For higher band scores (8+), using an appropriate tone not only helps you meet the formal and informal writing requirements but also demonstrates your ability to control your language based on the context.

Understanding Formal vs. Informal Tone

Formal Tone:
This is used when writing to someone you don’t know well or in professional or official contexts. Key features:
- Polite and respectful language
- Clear, structured sentences without slang or overly casual phrasing
- Professional salutation and closing
Example of a formal tone:
“Dear Sir/Madam, I am writing to formally request information regarding the accommodation facilities available in your esteemed organization.”
Informal Tone:
This is used when writing to a friend, family member, or someone with whom you have a personal relationship. Key features:
- Casual, friendly language
- Personal pronouns such as “I” and “you”
- Colloquial expressions or contractions (e.g., “I’ll,” “we’re”)
Example of an informal tone:
“Hey! Just wanted to let you know I’ll be in town next week. Can’t wait to catch up!”

How to use the Formal Tone in IELTS Writing Task 1?

Read the Question Prompt Carefully 🧐 To determine whether your letter requires a formal or informal tone, analyze the recipient and the context described in the question prompt.
- If you’re writing to a colleague, boss, or official entity, a formal tone is required.
- If you’re writing to a friend, a family member, or someone you have a personal relationship with, an informal tone is acceptable.
Example Formal Task:
“Write a letter to your landlord to complain about the noise in your apartment.”
- Formal tone is required since you are writing to an authority figure.
Example Informal Task:
“Write a letter to your friend about your new job.”
- Informal tone is required because the letter is to a friend.

Use Polite and Respectful Language for Formal Letters 🙏
- Polite Request:
  Use phrases like:
  - “I would appreciate it if…”
  - “I kindly request…”
  - “Could you please…”
  - “Would you mind…”
- Apologies and Gratitude:
  Use phrases like:
  - “I sincerely apologize for the inconvenience…”
  - “I would like to thank you in advance for your prompt response.”
- Formal Closing:
  Use professional closings like:
  - “Yours sincerely” (when you know the name of the recipient)
  - “Yours faithfully” (when you don’t know the name of the recipient)
Example of formal language:
“I would be grateful if you could address this matter at your earliest convenience. Yours sincerely, [Your Name]”

Avoid Casual or Slang Language in Formal Letters 🚫 Even in a more relaxed, informal letter, it’s important not to slip into slang or overly casual expressions. IELTS examiners expect you to use proper grammar and vocabulary, regardless of tone. Incorrect (Casual tone):
“Hey, I’m writing because the heating in my apartment is super bad. Can you fix it?” Correct (Formal tone):
“I am writing to inform you that the heating system in my apartment is not functioning properly. I would appreciate it if you could arrange for repairs.”

Tailor Your Language According to the Audience 🗣️
- For Formal Writing:
  Use formal phrases and precise language, with attention to professionalism and clarity.
- For Informal Writing:
  You may use contractions, and more personal or friendly expressions.

Common Mistakes to Avoid 🚫

Using Informal Language in a Formal Task:
If the question prompt asks for a formal letter, don’t use casual expressions or contractions. Stick to neutral or formal vocabulary. Incorrect: “Hi, I’m writing to let you know there’s an issue with the heating in my apartment.” Correct: “Dear Sir/Madam, I am writing to inform you about a problem with the heating system in my apartment.”
Overly Casual Salutations in Formal Writing:
Avoid addressing a professional or authority figure with casual salutations like “Hi,” “Hey,” or “Dear [First Name].” Always use formal greetings like “Dear Sir/Madam,” or “To whom it may concern.”
