This book is a gentle slope for those learning Hindi. As such, it gives the learner time to grasp the essence of the language and build a strong foundation on which to further progress. As many language learners know, compared to the major European languages and Japanese (and now Chinese), resources for many other languages are limited in both quality and quantity. The situation with Hindi is starting to change with the appearance of books such as this one and Delacy's Elementary Hindi, both of which teach Hindi in a systematic way with proper exercises and grammatical explanations. No doubt this book will provide a great foundation for intermediate Hindi study.
There is one problem with this book. I believe it is a significant problem. It doesn't negate the other good qualities of this book, which is why it still deserves 4 stars. Nonetheless, it is hard to use Hindi without knowledge of the normal past tense, as opposed to the past imperfect ("used to"). This book only talks about the past imperfect (I used to eat) and does not convey how to make a simple past sentence such as "I went." Now, this is related to a particle in Hindi that is often used with the past, "ne" which is probably one of the most difficult aspects of Hindi grammar for a beginner to grasp. However, it is not a nuance that can be delegated to a more advanced level since it is difficult to use any language without conjugating verbs in the past tense and this is simply the one aspect of Hindi grammar that one must slog through in order to grasp Hindi. Personally, I wish the past tense were included in this book, so that the habituation of students to it could begin, sooner rather than later.
