The book is a qualitative and quantitative investigation into the Catalan clitic system from Old to Modern Catalan. Building on the Minimalist Program, the author shows that a number of facts about Old Romance clitic placement that previously have either not been accounted for or have received unsatisfactory treatment can be explained in a principled way once a strict division of labor between syntax and phonology is adopted.

This volume explores in detail the empirical and conceptual content of agreement restrictions in grammar. It brings together different and relevant studies in this field and gives a general overview of the different theoretical approaches concerned with the morphological, syntactic and semantic properties of agreement restrictions in a series of European and Non-European languages.
