Is There a Comma Before Then?

“Is there a comma before ‘then’?” you might ask. Well, the answer isn’t as black and white as one might hope. It largely depends on how ‘then’ is being used in the sentence, which can make it seem like navigating through a minefield of commas and clauses! Let’s dive into this intriguing topic to eliminate any confusion that may arise when using this common conjunction.

What is the Purpose of a Comma?

Commas are critical players in our sentences. They might be small, but they hold great power and purpose. Here’s why:

  • Separation: Commas divide different parts of a sentence to make it easier to read.

    • Example: My dog enjoys running, barking, and playing fetch.
  • Listing: When you have several items in a series, commas help list them out.

    • Example: I need to buy apples, bananas, grapes, and oranges.
  • Joining Sentences: Commas allow us to connect related independent clauses using conjunctions.

    • Example: The movie was scary, but I enjoyed it.
  • Introducing Quotes or Direct Speech: We use commas before we introduce any quote or direct speech in writing.
    • Example: John said,”I will meet you at 6 PM.”

Here’s how these purposes stack up in tabular form:

Separation“My dog enjoys running, barking, and playing fetch.”
Listing“I need to buy apples, bananas, grapes, and oranges.”
Joining Sentences“The movie was scary, but I enjoyed it.”
Introducing Quotes/Direct Speech“John said, “I will meet you at 6 PM.””

Remember that understanding the purpose behind each comma helps create more meaningful sentences. It adds clarity when used correctly!

Commas for Sequential Actions

When it comes to sequential actions, the use of commas before “then” can be a bit tricky. Here are some situations and examples:

  • Two Independent Clauses: When “then” is used to connect two independent clauses, a comma should come before it.

    • Example: I went to the mall, then I had dinner at my favorite restaurant.
  • Dependent Clause Following an Independent Clause: If “then” introduces a dependent clause following an independent one, no comma is necessary.

    • Example: I finished my homework then started watching TV.

Here’s a handy table summarizing when you should use a comma before “then”:

SituationExampleComma Before “Then”
Two Independent ClausesI bought groceries, then cooked dinner.Yes
Dependent Clause After An Independent OneHe ran fast then caught the bus.No

Note: It’s always important to consider sentence structure when deciding whether or not to use a comma!

When to Use “Then” without a Comma

Sometimes, the word “then” is used without a comma. Here are a few instances where this happens:

  • Sequential Events: If “then” is used to denote sequential events or actions.


I woke up, brushed my teeth and then had breakfast.
  • Conditional Sentences: In conditional sentences where ‘if’ is followed by ‘then’.


If you're feeling unwell, then take a day off.
  • Comparative Statements: When creating comparative statements that compare one thing with another.


My car runs smoother than hers.

In these cases above, using commas before “then” can break the flow of the sentence or create unnecessary pauses. It’s simple – when in doubt about whether or not to use a comma before “then”, consider how it impacts your sentence’s readability and meaning.

Common Misuses of “Then” with a Comma

“Then” is often misused in sentences, especially when it comes to comma usage. Here are some common mistakes:

  • Using a comma before “then” when it’s not needed: Not every “then” needs a preceding comma. It’s only necessary if you’re indicating time or creating emphasis.

    Incorrect: I went to the store, then I came home.

    Correct: I went to the store then came home.
  • Adding a comma after “then” that doesn’t separate elements: Commas should be used sparingly and meaningfully. Don’t put one after “then” unless there’s an independent clause following it.

    Incorrect: Then, I realized my keys were still inside.

    Correct: Then I realized my keys were still inside.

Let’s summarize these points through few examples:

Incorrect UsageCorrect Usage
She ran quickly, then fell down.She ran quickly then fell down.
He bought flowers for his mom on her birthday, then he gave them to her.He bought flowers for his mom on her birthday then gave them to her.


1) Use commas with “then” only when separating two independent clauses or providing emphasis.
2) Avoid unnecessary commas before or after “then.”

Guidelines for Using Commas with “Then”

When it comes to using commas before “then”, there are a few important considerations.

  • Sentences starting with “then”: If you’re starting your sentence with ‘Then’, don’t use a comma.
Then we decided to go out for dinner.
  • ‘And then’ combinations: When ‘and’ precedes ‘then’, again, no need for a comma.
She finished her homework, and then she went to the playground.
  • Sequential events: In case of sequential activities where ‘then’ is used, apply no comma.
I woke up, brushed my teeth then had breakfast.


  • Compound sentences: For compound sentences where ‘then’ connects two independent clauses, use a comma before ‘then’.
She was tired from work, then she still had to cook dinner.
  • Contrasting statements: A contrasting situation following ‘then’ calls for a comma.
It's not about winning the race, then losing yourself in the process.

Remember that context plays an important role when deciding whether or not to use a comma before “Then”.

Wrapping Up the Comma Conundrum

In the end, it’s clear that whether to place a comma before “then” is not carved in stone. The choice hinges on your sentence structure and meaning you intend to convey. A comma becomes necessary when ‘then’ functions as part of an introductory clause or separates independent clauses.

However, if ‘then’ is merely connecting two related actions within one clause, ditch the comma. Remember, clarity should be your guidepost here. Always reread your sentences to ensure they make sense and don’t lead to confusion.

So next time you find yourself hesitating over hitting that comma key before typing ‘then’, ask yourself about its role in the sentence. If it’s paving way for a new thought or action distinct from what preceded, go ahead with the pause (comma). But if it simply links two ideas without needing any breath-catching stopover – give that comma a miss! It’s all about context and clarity.
