"This book is an important 'must read' contribution both to contemporary syntactic theory and to the description and analysis of understudied Berber dialects. It illuminates fundamental aspects of syntactic theory and Minimalist method analyzing phenomena of enduring interest, including (Anti-) Agreement, Cliticization and Negative Concord while insightfully revealing their possible unification and deduction as facilitated by adopting and further clarifying certain central formal aspects of current Minimalist analysis."
