Kinds of Sentences
What kinds of sentences shall a speaker construct as he speaks? That there is a difference between those a person composes when he writes and those the same person is likely to evolve when he speaks is realized by everyone. We hear that a speaker is "booky," or conversational, that he is stilted or lively, that he is too formal, that his discourse is dull and flat. To a great degree these criticisms are based upon the sentence structure.
