Introducción a la lingüística española
I have used this text to teach Spanish linguistics at the introductory level for several semesters now, and have found it to be awesome in respect of the the information it provides; additionally, the exercises for students. Needless to say, the language used is far from abstract, that is to say: easily accessible to students. For these and many more reasons, I should like to recommend the above-mentioned text to both student and teachers!
