Understanding and Fixing Comma Splices

All writers have been there at some point: the dreaded comma splice sneaks into our sentences, leaving us wondering what went wrong. If you've ever received feedback like "this is a run-on sentence" or "fix the comma splice," don't worry—you're not alone. In this post, we'll explain comma splices and why they're an issue, as well as show you how to fix them like a pro.

What Is a Comma Splice?

A comma splice occurs when two independent clauses (complete thoughts) are joined together with just a comma.

Example of a comma splice:

I love the challenge, it helps me write my novel.

In this example, "I love writing" and "it helps me express myself" are both independent clauses. A comma by itself cannot properly connect them.

Why Are Comma Splices a Problem?

Comma splices can make your writing feel rushed or confusing because they don't clearly show the relationship between ideas. They can also make your sentences harder to read, especially in professional or formal writing.

That said, some authors use comma splices stylistically in creative writing, but this requires careful intention and skill.

How to Fix a Comma Splice

Luckily, fixing a comma splice is easy once you recognize it. Here are four simple solutions:

1. Replace the comma with a period. Break the sentence into two separate sentences.

   I love the challenge. It helps me write my novel.

2. Replace the comma with a semicolon. Use a semicolon to connect the two clauses if they're closely related.

   I love the challenge; it helps me write my novel.

3. Add a coordinating conjunction. Use words like "and," "but," "or," "so," or "yet" to join the clauses properly.

   I love the challenge, and it helps me write my novel.

4. Rephrase the sentence. Rewrite the sentence to eliminate the need for a comma.

   The challenge helps me write my novel, and I love it.

How to Avoid Comma Splices in the Future

• Identify independent clauses: Ask yourself if each part of the sentence can stand alone as a complete thought.

• Read your sentences aloud: If you naturally pause where a comma is, double-check that it’s being used correctly.

• Learn punctuation rules: Familiarize yourself with semicolons, periods, and conjunctions to confidently structure your sentences.

• Use grammar tools: Software like Grammarly or ProWritingAid can help catch comma splices in your writing.

Final Thoughts

Comma splices are a common writing mistake, but they’re also easy to fix once you understand how punctuation works. Whether you’re writing a novel, an essay, or a social media post, clear and correct sentences make all the difference.

Remember: punctuation isn’t just about following rules—it’s about making your writing as effective and impactful as possible. Once your work is published and in the readers' hands, you can't explain what you meant. Taking the time to master punctuation, including avoiding comma splices, ensures your ideas are delivered clearly and leave a lasting impression.
