In elementary school, high school, and even a freshman college English course, I diagrammed sentences. It was a logical, almost mathematical approach to sentence structure and grammar, and it was one of the few useful exercises thrust upon unwitting students by the public school system. Unfortunately, the sentence diagram is going the way of cursive writing classes and phonics.
Lucky for us dinosaurs, there’s a new book out about the dying practice. Sister Bernadette’s Barking Dog: The Quirky History and Lost Art of Diagramming Sentences written by Kitty Burns Florey, explores the world of diagramming with a nostalgic eye. NPR reviews.
