I frequent the Chicago Manual of Style fairly often at work.
Today, under section 5.191 (you know the one), I came across this quote that they actually were hilarious enough to include in their official, peer-reviewed guidance on "Beginning a Sentence with a Conjunction." It comes from Charles Allen Lloyd, “Next to the groundless notion that it is incorrect to end an English sentence with a preposition, perhaps the most wide-spread of the many false beliefs about the use of our language is the equally groundless notion that it is incorrect to begin one with ‘but’ or ‘and.’ As in the case of the superstition about the prepositional ending, no textbook supports it, but apparently about half of our teachers of English go out of their way to handicap their pupils by inculcating it. One cannot help wondering whether those who teach such a monstrous doctrine ever read any English themselves.”
Well ok then.
I just love the keywords, “groundless notion,” “handicap,” and “monstrous” because Charles is berating me and not only do I deserve it, but I want his approval now more than ever. Take notes teacher roommates. The abuse cycle is the only way to educate.
