Comma Splices​

​

​Objectives

​At the end of the lesson, you should be able to:

​

• ​Recall fragments and run-ons

• ​Identify comma splices

• ​Correct errors

​What is a comma splice?

• A comma splice occurs when you use a comma to join two complete sentences without placing an appropriate joining word between them.​

• ​The comma just isn't strong enough to do the job of making one grammatical sentence out of two.

I completed my essay, I have not submitted it.​

​

​This is a comma splice because the comma is between two independent clauses without a FANBOY.

​Corrected: I completed my essay, but I have not submitted it. 

​Can you tell the difference between the errors?
