Fix Grammar Errors Instantly with Our Free Comma Splice Checker Tool
A comma splice is one of the most common grammar mistakes found in essays, emails, articles, and professional documents. It occurs when two complete sentences are incorrectly joined by just a comma. This disrupts the flow of your writing and can confuse your readers.
Our Comma Splice Checker detects these sentence-level issues in seconds—helping you write clearly, confidently, and correctly.
What Is a Comma Splice?
A comma splice happens when two independent clauses (complete sentences) are joined only with a comma, without a coordinating conjunction (like and, but, so) or a semicolon.
Example:
Incorrect: “I enjoy writing, it helps me think.”
Correct: “I enjoy writing. It helps me think.”
Why Fixing Comma Splices Matters
Comma splices weaken your writing by:
- Breaking sentence structure
- Creating confusion for the reader
- Making professional or academic work look unpolished
In formal settings—such as academic papers, resumes, or business communication—a single comma splice can affect your credibility. That’s why it’s crucial to spot and fix these mistakes before publishing.

4 Ways to Fix a Comma Splice
1. Use a Period
Break the sentence into two separate sentences.
Example:
Incorrect: “He writes well, he practices daily.”
Correct: “He writes well. He practices daily.”
2. Add a Coordinating Conjunction
Use words like and, but, or, so, yet, for, nor after the comma.
Correct: “He writes well, and he practices daily.”
3. Use a Semicolon
Use a semicolon to link two related independent clauses.
Correct: “He writes well; he practices daily.”
4. Make One Clause Dependent
Convert one of the independent clauses using subordinating conjunctions like because, although, or since.
Correct: “Because he practices daily, he writes well.”
