The subjunctive is more than a trap for unwary students; it is truly a key component of the Spanish language, a basic structure that the whole language depends on. Condorito comic strips provide the basis for the Spanish grammar examined in this book as they perfectly capture fleeting colloquial Spanish in a permanent concrete form. This book is an invaluable resource for mastering Spanish grammar because although native speakers control the subtle nuances of the subjunctive mode perfectly, they cannot explain it. The explanations in this book encourage the learner to extrapolate and expand on the particular grammar point being presented.
