A comma splice occurs when two complete sentences are joined only by a comma—without the right conjunction or punctuation. It’s a common writing mistake that can confuse readers or make your writing feel unpolished.
Example of a comma splice:
I love to write, it's my favorite hobby.
This sentence includes two independent clauses (complete thoughts) joined incorrectly by a comma.
How to Fix a Comma Splice
Here are three simple ways to correct a comma splice:
Use a period:
I love to write. It’s my favorite hobby.Use a semicolon:
I love to write; it’s my favorite hobby.Use a coordinating conjunction (like and, but, or so):
I love to write, and it’s my favorite hobby.
Are Comma Splices Ever Acceptable?
In most cases—especially in formal, academic, or professional writing—comma splices are considered errors. Editors and publishers usually expect them to be corrected before publication.
However, there are some exceptions in today’s publishing world:
Creative writing: Some fiction writers use comma splices intentionally to create a conversational tone or a sense of urgency.
She ran to the door, she didn’t look back.
Dialogue: People often speak in run-ons, so comma splices in dialogue can reflect natural speech patterns.
Even in these cases, the key is to use them sparingly and intentionally. Overusing comma splices—or using them by accident—can make your writing feel sloppy rather than stylish.
Final Tip
Know the rules before you bend them. In most writing, fix comma splices to ensure your ideas are clear and your prose is polished. If you choose to use them creatively, make sure it’s a conscious decision that fits your voice and purpose.
