Why Do We Write Letters?
People have been writing letters for a very, very long time! Long before we had phones or computers, letters were the only way to send a message to someone far away. A person would write words on paper, fold it up, and send it to a friend or family member. Over time, people agreed on special rules so that every letter would be easy to read. One of those rules is about using commas.
So here is the big question: Where exactly does the comma go in a letter? That is what this lesson is all about. Let's find out!
The Two Comma Rules for Letters
Every letter has two special parts that need a comma. The first part is the greeting (also called the salutation). The second part is the closing. Let's learn what each one means.
The Greeting
The Closing

What Comes Next
See It! — A Letter with Commas
Let's look at a picture of a real letter. See if you can spot the two commas!
Did you see the two red commas? The first comma comes right after Dear Grandma — that is the greeting. The second comma comes right after Love — that is the closing. The body of the letter (the middle part) does not need a special comma at the start or end.
How It Works — Step by Step
Writing a letter is like building a sandwich. You need the top piece of bread (the greeting), the filling in the middle (the body), and the bottom piece of bread (the closing and your name). The commas are like the toothpicks that hold each piece in place!
Here is the pattern you should follow every time you write a letter:
Remember: the comma always goes right after the greeting words and right after the closing words. No comma after your name at the very end!
Types of Greetings and Closings
There are many different ways to say hello and goodbye in a letter. No matter which words you pick, the comma rule stays the same. Here are some common greetings and closings you might use.
| Greetings (Hello Words) | With Comma ✓ |
|---|---|
| Dear Mom | Dear Mom, |
| Dear Mr. Lee | Dear Mr. Lee, |
| Dear Best Friend | Dear Best Friend, |
| Hi Jake | Hi Jake, |
| Hello Class | Hello Class, |
| Closings (Goodbye Words) | With Comma ✓ |
|---|---|
| Love | Love, |
| Your friend | Your friend, |
| Sincerely | Sincerely, |
| Thank you | Thank you, |
| See you soon | See you soon, |
Notice that every single greeting and every single closing gets a comma at the end. It does not matter how long or short the words are. Even a tiny closing like Love, needs a comma!
Worked Example — Write a Letter Together
Let's write a short letter to a friend named Lily. We will go step by step and put the commas in the right places.
I miss you! Do you want to play at the park on Saturday? We can bring our bikes.
I miss you! Do you want to play at the park on Saturday? We can bring our bikes.
Your friend,
I miss you! Do you want to play at the park on Saturday? We can bring our bikes.
Your friend,
Emma
🎉 Great job! Our letter has two commas — one after the greeting and one after the closing. That is exactly right!
Right vs. Wrong — Common Mistakes
Let's look at some common mistakes kids make when writing letters. Can you tell what is wrong before reading the answer?
| Wrong ✗ | Right ✓ | Why? |
|---|---|---|
| Dear Dad (no comma) | Dear Dad, | The greeting always needs a comma at the end. |
| love, (lowercase L) | Love, | The closing starts with a capital letter. |
| Your Friend. (period) | Your friend, | Use a comma, not a period, after the closing. |
| Dear, Mom, (extra comma) | Dear Mom, | Only one comma — after the whole greeting, not in the middle. |
| Sincerely (missing comma) | Sincerely, | Don't forget the comma after the closing! |

What We Learned
In this lesson, you learned that every letter has two places that need a comma. The first comma goes at the end of the greeting — that's the hello part at the very top, like Dear Mom, or Hi Jake,. The second comma goes at the end of the closing — that's the goodbye part near the bottom, like Love, or Your friend,. After the closing comma, you write your name on the next line.
Remember the "Two-Comma Check" every time you write a letter: one comma after the greeting and one comma after the closing. The comma is like a little wave — hello 👋 and goodbye 👋. Now you are ready to write wonderful letters to anyone!
