The Period. There’s not much to be said about the period except that most writers don’t reach it soon enough. If you find yourself hopelessly mired in a long sentence, it’s probably because you’re trying to make the sentence do more than it can reasonably do—perhaps express two dissimilar thoughts. The quickest way out is to break the long sentence into two short sentences, or even three. There is no minimum length for a sentence that’s acceptable in the eyes of God.
