The comma splice is considered as one of the most common grammar errors that beginning and intermediate English writers are guilty of. Don’t worry, though. It’s also one of the easiest mistakes to remedy.
As you probably know, a clause is a group of words with a subject and a predicate that can be used as a simple sentence or as a part of a complex one. A comma splice is the act of joining two of these independent clauses by using a comma without employing a conjunction.
When A Comma Splice Is Correct
A comma splice “may” be acceptable when two clauses that use the same subject are used to demonstrate contrast. For instance, saying “I am not John, my name is Perry” is perfectly correct.
Correcting A Comma Splice
Generally, though, you will want to avoid comma splices just to err on the safe side. If you find comma splices used throughout you writing, you can edit them by doing one of the following:
1. Replace the comma with a period. Basically, this turns the sentence into two simple sentences. It’s not the best solution as your text will likely read very elementary, although it’s a valid option.
2. Insert a conjunction to connect the two clauses. Adding a conjunction may be the best way to remedy it, allowing you to keep the look and feel of your writing, while allowing to pass the watchful eye of your grammar software.
3. Replace the comma with a semi-colon. A semi-colon is the standard way of connecting two clauses that aren’t joined by a conjunction.
