There is a widespread belief—one with no historical or grammatical foundation—that it is an error to begin a sentence with a conjunction such as, and, but, or so. In fact, a substantial percentage (often as many as 10 percent) of the sentences in first-rate writing begin with conjunctions. It has been so for centuries, and even the most conservative grammarians have followed this practice. Unquote.
