Does the comma come before but or after

Should you use a comma before but or after but?

You should use a comma before but whenever you’re connecting two independent clauses. It’s much rarer to use a comma after but.

In this article, we explain this comma rule and give you examples of sentences that use commas before and after but.

Do You Put the Comma Before or After But?

There are three possible situations you might encounter when it comes to using a comma with the word but.

You might need to use a comma before but, you might need to use a comma after but, and you might not need to use a comma at all.

Let’s look at each of these punctuation rules in more detail.

Comma Before But

You should use a comma before but if you’re using the word but to connect two independent clauses.

An independent clause is a string of words that can stand on its own as a complete sentence, with a subject and an object.

For example, “I love food” and “I hate cooking” are both independent clauses.

If you join those two independent clauses with a conjunction, such as “and,” “or,” or “but,” you should use a comma where the period would have been after the first independent clause.

For example, you would use a comma in this sentence: “I love food, but I hate cooking.”

Here are a few more examples of cases when you need to include a comma before but:

• I have a gym membership, but I rarely use it.
• This restaurant has great service, but the food is quite expensive.
• You’re a very nice person, but I only see you as a friend.

Notice that all of the above examples use the word but to connect two independent clauses, both of which could stand alone as complete sentences.

No Comma Before or After But

You don’t need to use a comma before or after but if you’re connecting an independent clause with a dependent clause.

We defined independent clauses earlier. A dependent clause, in contrast, is a string of words that doesn’t form a complete sentence.

For example, the phrase, “only if it’s well-cooked” is a dependent clause. Thus, you wouldn’t use a comma in the following sentence: “I love food but only if it’s well-cooked.”

Here are some other examples of cases when you don’t need a comma:

• Sarah has seven cats but only one dog.
• You had a birthday party but didn’t tell me about it?
• I’m very busy but not because of work.

Notice that in each of the above examples, the clause that follows the word but is dependent, meaning it isn’t a grammatically complete sentence on its own.

Comma After But

Using a comma after but is much rarer than using a comma before but.

You should only do this when you’re interrupting the sentence flow with another word or clause immediately after the word but, to create emphasis.

For example, you might write, “But, my dear, you didn’t tell me the whole story.” In this case, the phrase “my dear” is an interrupter that adds dramatic literary effect.

Here are some other examples of cases when you might include a comma after but:

• “But, as you know, the dodo bird went extinct long ago.”
• “I enjoyed the book, but, to be honest, I didn’t completely understand it.”
• “I tried to go to the grocery store, but, as it turns out, it closed early.”

Notice that all of the above examples include an interrupter immediately after the word but.

Remember that this is a rare situation, so most of the time, you should avoid using a comma after but.
