The best-selling style book, Style: Ten Lessons in Clarity and Grace, Seventh Edition , presents principles of writing to help students diagnose their prose quickly and revise it effectively.

The four sections—Style as Choice, Clarity, Grace, and Ethics—feature new principles of effective prose, chapter summaries for quick and easy review, and group exercises that encourage students to work and learn together. Williams offers these principles as reason-based approaches to improving prose, rather than hard and fast rules to writing well. Style, 7/e, empowers students to use their writing not only as a tool to identify and solve problems, but also as a method for exploring their own thinking.
