Chi Luu hits home with the article, "Dear Pedants: Your Fave Grammar Rule is Probably Fake" on JStor Daily:

"It seems pretty crazy but the popular grammar rules familiar to most of us may in fact be completely fake and have no basis in linguistic reality. The English language didn’t change to make those rules obsolete, they were simply fictional from the start."

Now I can split infinitives in peace.
