See if you can identify what's wrong with this sentence: Larry slammed the refrigerator door, he vowed never to buy Roquefort cheese again.
Okay, other than Larry's deep-seated aversion to Roquefort--which may suggest psychological issues--we've got another problem. Duh duh DUUUUHHHH . . . a comma splice.
See, the problem with a comma splice is that it's used between independent clauses. If they're independent they should be standing alone. As in their own sentence. Or at least joined together by a nice coordinating conjunction. Comma splices can confuse the reader who no doubt innately knows that commas only belong with dependent clauses. (Yep.)
Four ways to "fix" a comma splice:
1) Substitute that sucka for a period and capitalize the next word. Larry slammed the refrigerator door. He vowed never to buy Roquefort cheese again.
2) Substitute that sucka for the under-utilized but highly practical semicolon! (Semicolons join independent clauses! Whoot Whoot!) Larry slammed the refrigerator door; he vowed never to buy Roquefort cheese again.
3) Keep the comma, but add a conjunction to the beginning of the second independent clause. Larry slammed the refrigerator door, and he vowed never to buy Roquefort cheese again.
4) Keep the comma, but make one of the independent clauses dependent (meaning it NEEDS another thought to make it complete--don'tcha just hate when people and clauses are so stinkin' needy?!). Slamming the refrigerator door, Larry vowed he would never buy Roquefort cheese again. OR Larry slammed the refrigerator door, vowing he would never buy Roquefort cheese again.
So see? With so many correct ways to convey the same idea, there's really no good excuse for a comma splice.
AND after typing this Friday Fix, I can now spell "Roquefort" in my sleep! YAY! I love it when there are multiple perks! :-)
