I’m Keith Folse. I’m an author, teacher, traveler and lifelong language learner. I’ve written more than 80 books on vocabulary, grammar, writing, and other areas of English teaching and learning. My books are used in classrooms around the world and have sold millions of copies in four languages.
In recent years, I’ve expanded my work to include the Smart Travel Books series—clear, practical guides to help travelers make better travel decisions.
Whether you’re a teacher, a student, or a traveler, my goal is simple: to help you learn more, teach better, and explore the world with confidence.
