It’s not enough to know the parts of speech. One needs to know the best way to employ them in order to write clearly and effectively. This textbook contains 56 rules of English usage divided into rules of brevity and rules of clearness and force. Several sets of exercises enable students to practice proper composition techniques. Written by an English grammarian, teacher and schoolmaster, this book is intended for use both in the classroom and for homeschooling. A companion volume, “How to Parse,” explains English grammar in greater depth.
