I originally bought this book to give to a bilingual friend who is interested in language and word origins. The book is well written, informative and entertaining. However, when I started going through it, I realized that the book is too basic for bilingual Spanish-English speakers. There are a few surprises (barrio has an Arabic origin!) but overall fluent Spanish speakers will find little of interest. Instead, it's a very good book for beginner Spanish speakers who want to know more about the language, or for anybody interested in the history of words used everyday in the US.
