Book excerpt: The first usage-based approach of its kind, this volume contains twelve studies on key issues in Spanish syntax: word order, arguments, grammatical-relation marking, inalienable possession, ser and estar , adjective placement, small clauses and causatives. The studies are approached within a broad functionalist perspective. The studies strengthen the view that components of grammar intricately interact and that a usage-based approach to analyzing them offers new and insightful perspectives on some stubborn problems.
