How to Fix Comma Splices

A comma splice joins two independent clauses with only a comma. Each clause can stand as a complete statement. For example: “The report is ready, I will send it today.”

The problem is the connection between the clauses. You can repair it in several ways, depending on their relationship.

Use a full stop

“The report is ready. I will send it today.” This gives each idea its own boundary. It works well when you want a direct, easy-to-scan message.

Add a coordinating conjunction

“The report is ready, and I will send it today.” The conjunction makes the connection explicit. Words such as “but” and “so” express different relationships; choose the one that matches your meaning.

“The report is ready, but the appendix needs work” expresses a contrast. Replacing “but” with “so” would change the logic.

Use a semicolon for closely related clauses

“The report is ready; I will send it today.” Both sides must still be complete clauses. A semicolon is not a substitute for every comma in a long passage.

Make one clause dependent

“Since the report is ready, I will send it today.” This explains the reason for sending it. Use this version only when that causal relationship is what you mean.

Review the paragraph

Varying punctuation can improve flow, but accuracy comes first. Check that each revision keeps the original relationship between ideas. The run-on sentence checker can suggest boundaries; you decide which version fits the paragraph.
