This unique reference equips students with vocabulary skills that will last a lifetime. Students study Latin and Greek roots and learn the huge number of English words that derive from them. The impressive number of entries and explanations, presented in a light and non-threatening manner, will give students the vocabulary boost they need.
Although this isn't really a kids book, I'm using this to help my kids understand language better. A few puzzling omissions, but still more often useful than not. You take an English word (e.g., "civic"), look it up in the back to find the Latin/Greek root ("civis"), then turn to the entry for "civis" to learn what other words are related to it. Fun for all the family.
I got this book to learn origins for vocabulary, but I didn't read too much of it before I got another vocab book and another, before not reading any of them much at that time. It is pretty cool though.
