This text is a compilation of articles on different aspects of Spanish grammar in the areas of current theoretical syntax and semantics. Topics covered include: the syntax and semantics of clitics and clitic doubling; the structure of noun phrases, with special attention to adjectives; the position of subjects; tense and causation. The approaches fall within generative grammar, broadly understood, with some contributions cast in the perspective of the minimalist program. Thus, the book attempts to offer a balanced picture of state of the art research in these areas. Luis Silva-Villar is Assistant Professor of Hispanic Linguistics at Mesa State College, USA.
