Since I am thinking about grammer and language usage this morning, I thought I would share 5 grammar rules that never existed (or that have been incorrectly interpreted). Steve Tollefson points these out in an article written for Writing Across Berkeley, a forum on teaching writing at U.C. Berkeley. Here are the rules he debunks:
You can't start a sentence with "and" or "but."
Sentence fragments are never acceptable.
You must never split an infinitive.
You must never end a sentence with a preposition.
What follows a colon is always a list.
