A book to improve vocabulary. I bought this book after learning that American high school students also use it to improve their vocabulary. It's a book that uses etymology to help you learn words, which makes it enjoyable (for example, "ped-" comes from the Latin word for "walk," so "pedestrian" means "walker," etc.), but I've only flipped through it and it's been stored on the bookshelf. No writing inside. There is some slight soiling on the cover (where a price sticker was removed).
