What is a Comma Splice?

A comma splice happens when two independent clauses (complete thoughts that could stand alone as separate sentences) are joined by a comma, but there is no coordinating conjunction like "and," "but," or "or," or no punctuation like a semicolon to properly separate the clauses.

• Incorrect Example (Comma Splice):
  • I went to the park, I saw my friends.
    In this sentence, two independent clauses—"I went to the park" and "I saw my friends"—are connected by a comma, which is not grammatically correct.

Why Is a Comma Splice a Problem?

Comma splices create confusion and disrupt the flow of a sentence. When two independent clauses are improperly connected by a comma, it can make the sentence harder to read and understand. While the error may seem minor, it breaks the rules of sentence structure, making the writing feel unpolished.

Common Comma Splice Examples

Here are some common examples of comma splices to help illustrate the mistake:

1. Example 1:

   • I wanted to go shopping, I didn’t have enough money.
     (Comma splice: "I wanted to go shopping" and "I didn’t have enough money" are two independent clauses joined by a comma.)

2. Example 2:

   • She loves to read, she always has a book in her hand.
     (Comma splice: "She loves to read" and "she always has a book in her hand" are both independent clauses incorrectly connected with a comma.)

3. Example 3:

   • The sun is setting, the sky is turning orange.
     (Comma splice: "The sun is setting" and "the sky is turning orange" are independent clauses incorrectly joined by a comma.)

How to Fix a Comma Splice

There are several ways to correct a comma splice and turn it into a grammatically correct sentence. Below are the most common methods:

1. Use a Period to Separate the Clauses

The simplest and most straightforward fix is to separate the two independent clauses with a period, making them two complete sentences.

• Corrected Example:
  • I wanted to go shopping. I didn’t have enough money.

By turning the comma into a period, we ensure that each clause stands on its own as a complete sentence.

2. Use a Semicolon to Join the Clauses

Another way to correct a comma splice is by replacing the comma with a semicolon. A semicolon joins two related independent clauses without the need for a coordinating conjunction.

• Corrected Example:
  • I wanted to go shopping; I didn’t have enough money.

A semicolon is appropriate when the two independent clauses are closely related in meaning, as in this case.

3. Add a Coordinating Conjunction

You can also fix a comma splice by adding a coordinating conjunction like "and," "but," "or," "yet," or "so" after the comma. This connects the two clauses in a grammatically correct way.

• Corrected Example:
  • I wanted to go shopping, but I didn’t have enough money.
  • She loves to read, so she always has a book in her hand.

By adding a coordinating conjunction, you show the relationship between the two clauses and properly connect them.

4. Use a Subordinating Conjunction

If the second clause provides additional, non-essential information, you can convert one of the independent clauses into a dependent clause by adding a subordinating conjunction (e.g., "because," "although," "if," "when," etc.).

• Corrected Example:
  • I wanted to go shopping because I didn’t have enough money.
  • She loves to read, although she doesn’t have much time.

By changing one clause into a dependent clause, you eliminate the comma splice while maintaining the meaning of the sentence.
