Comma Splices

How to Identify and Fix Comma Splices

 

What is a Comma Splice?

 
A comma splice occurs when two independent clauses in a sentence are separated by a comma that is not followed by a conjunction.

For those who are unfamiliar with these terms, an independent clause is a phrase that can stand alone as a grammatical sentence. A very simple independent clause would be: “I slept.”

A conjunction is a word that can join two words or clauses. Examples of common conjunctions are: although, and, but, because, or, so, unless, until, when, while, and yet.

Let us now look at an example of a comma splice:

  • “I was sick, I slept all day.”

This sentence is ungrammatical because it contains two separate independent clauses — both “I was sick” and “I slept all day” can stand alone as full sentences. These two clauses are separated only by a comma, and a comma is not strong enough to separate two independent clauses.
 

Four Ways to Fix a Comma Splice

 
1) The simplest way to fix a comma splice is to change the comma to a period and then ensure that the letter which follows the period is capitalized.

  • “I was sick. I slept all day.”

2) Similarly, and more effectively if the two clauses are closely related (as they are in our example), you can replace the comma with a semi-colon. Semi-colons are commonly used to indicate that two sentences are closely related to each other.

  • “I was sick; I slept all day.”

3) Another way to fix a comma splice is to replace the comma with a coordinating conjunction (or to insert a conjunction after the comma).

  • “I was sick and I slept all day.”
  • “I was sick, so I slept all day.”

4) A conjunction does not need to be placed between the clauses for it to fix a comma splice. A comma splice can also be fixed by placing an appropriate conjunction at the beginning of the sentence.

  • Because I was sick, I slept all day.”
