What really goes on inside a sentence? What is your subject, and where is your verb, and what is its tense, and where is your modifier, and why does it matter? Where do you need a comma, and where do you not? Why are dashes and semicolons so misunderstood? When is it which and when is it that? In The Little Green Grammar Book , Mark Tredinnick asks and answers the tough grammar questions--big and small--with the same verve and authority readers encountered in The Little Red Writing Book . The Little Green Grammar Book does for grammar what The Little Red Writing Book did for style. It will have you writing like a writer in no time.
