Complete Lesson: Writing Formal Letters (Master Formal Letters for School, Office, and Organizations)
A formal letter is a written message used for official, professional, or serious purposes — such as writing to a school, an office, a company, or an organization. Unlike personal letters or emails, formal letters follow a strict structure and use polite, professional language.
Part 1: What Is a Formal Letter?
A formal letter is written for official purposes, such as applying for a job or leave, writing to a school principal or teacher, making a complaint to a company, requesting information from an organization, or writing to a government office.
| Formal Letter | Informal/Personal Letter |
|---|---|
| Polite, professional tone | Friendly, casual tone |
| Follows a fixed structure | Flexible structure |
| No short forms (do not, cannot) | Short forms allowed (don't, can't) |
| Starts with "Dear Sir/Madam" | Starts with "Hi" or "Dear [Name]" |
| Signed with full name and title | Signed with first name only |
Part 2: Structure of a Formal Letter
A formal letter has specific parts ordered sequentially from the sender's address down to the signature.

Part 4: Salutations (Greetings) and Closings
Salutations
| When to use | Salutation |
|---|---|
| You don't know the name | Dear Sir/Madam, |
| You know the name (male) | Dear Mr. [Last Name], |
| You know the name (female) | Dear Ms./Mrs. [Last Name], |
| Writing to an organization | To Whom It May Concern, |
| Writing to a principal | Respected Sir/Madam, / Dear Principal, |
Closings
