A comma splice is an incorrect use of a comma to connect two independent clauses (complete thoughts) without the appropriate conjunction or punctuation. It is considered a type of run-on sentence error.

To identify and correct a comma splice, follow these steps:

1. Look for a comma separating two complete thoughts. For example: "I went to the store, it was closed."
2. Determine if the thoughts can stand alone as separate sentences. If they can, they are independent clauses.
3. If there is a comma but no appropriate conjunction (such as "and," "but," "or," etc.) or punctuation (such as a semicolon or period) between the clauses, it is a comma splice.
4. To correct a comma splice, you can use one of the following methods:
- Separate the clauses into separate sentences: "I went to the store. It was closed."
- Use a coordinating conjunction to connect the clauses: "I went to the store, but it was closed."
- Replace the comma with a semicolon: "I went to the store; it was closed."

Remember that a comma splice is incorrect usage and should be avoided to maintain clear and concise writing.
