This book is the definitive demystifier of the Spanish verbs SER and ESTAR. The beginning to the advanced student will discover all of the subtleties and nuances of the two 'to be' verbs, as well as dozens of lively dialogues to reinforce appropriate usage. Written in a clear and entertaining style, the book has invaluable information for all students of Spanish from the beginner to the fluent speaker.
I picked this book up when I was taking my first Spanish class. These verbs are difficult to master (they both mean "to be") for a non-native Spanish speaker even after years of practice, but this book provides a great foundation! Highly recommended to those studying Spanish. It may be a little advanced for beginners, but it is very helpful for later success.
