Nib #143 Back to Basics: The Comma Splice
“No comma splices” is one of those ubiquitous writing tips everyone has heard… but most young writers today don’t understand. (“It’s not your fault, Will. It’s the education system’s.”)

So, what is a comma splice? It’s the grammatical mistake of trying to link two independent clauses with just a comma and no helping word. Like this:
Rover was a beagle, he was a good boy.
Both independent clauses here are fine. The problem is linking them with just a comma. There are lots of correct ways you could present these clauses.
If you’re sure you want to connect them in the same compound sentence without a linking word, you need a semicolon, not a comma (IC; IC):
Rover was a beagle; he was a good boy.
If you wanted that extra beat of a short linking word, you could keep the comma and add a coordinating conjunction (IC, cc IC):
Rover was a beagle, and he was a good boy.
Or you could, Hemingway-style, just make them two simple sentences:
Rover was a beagle. He was a good boy.
But the one thing you can’t do is splice two independent clauses together with a comma. Now you know.
Until next week… keep writing!
