The objective of this book is to teach native speakers of Spanish how to write and use correctly their own language. This text is designed for Spanish speakers who also know English. Current methodology in the teaching of Spanish to Spanish speakers is based on the belief that native speakers already know Spanish and that such students primarily need to polish their orthography. The book stresses traditional but advanced grammar as well as accentuation, orthography and the avoidance of anglicisms in vocabulary and sentence structure. It draws from the students' linguistic background in both languages in order to teach them Spanish.
