Designed to teach Spanish through an understanding of English grammar, this title helps students who may not have had a grounding in English grammar understand how their own language works and how it can be applied to another language. The fifth edition offers an explanation of a concept as it applies to English and then details the same concept as it applies to Spanish. It explores similarities and differences between English and Spanish and highlights common pitfalls for English speakers. The guide also features review exercises with an answer key and study tips ranging from learning vocabulary and word forms to developing memorization skills.
