<p>It is a common theme for the SAT to use comma splices in incorrect answer choices. A comma splice is a grammatically incorrect use of a comma to join two independent clauses.</p>
<p>Here are some incorrect sentences that use comma splices:
“I ate a large dinner, later, I had a stomach ache.”
“I ate a large dinner, as a result, I had a stomach ache.”
“I ate a large dinner, I had a stomach ache.”</p>
<p>Here are multiple ways of fixing this error:</p>
<p>Semicolon:
“I ate a large dinner; later, I had a stomach ache.”
“I ate a large dinner; as a result, I had a stomach ache.”</p>
<p>Period:
“I ate a large dinner. Later, I had a stomach ache.”
“I ate a large dinner. As a result, I had a stomach ache.”</p>
<p>Coordinating Conjunction:
“I ate a large dinner, and, later, I had a stomach ache.”
“I had eaten a large dinner, so I had a stomach ache.”
(Commas work because the conjunctions “and” and “so” are used, connecting their two respective clauses directly. “However” does not do this.)</p>
<p>Could you tell me which of the following sentences are correct and incorrect</p>
<p>I was late to the show, however, I met my best friend.
I was late to the show. However I met my best friend</p>
<p>I was late to the show. I met my best friend, however
I was late to the show; I met my best friend however.
I was late to the show; I met my best friend, however.
I was late to the show. I met, however, my best friend.</p>
<p>The first one is incorrect: it has a comma splice. You can’t link two independent clauses (i.e., subject + verb) without a coordinating conjunction (e.g., and, or, but, yet). </p>

<p>The second one needs a comma before however. The fourth one sounds really awkward (unlike the analogous example I gave earlier); that sentence doesn’t work well with a conjunctive adverb in the middle.</p>
