This book is concerned with a number of central issues in the theory of clitics, a topic that has become much debated in recent years. Mainly written within a recent generative framework, its contrastive approach discusses these issues against the background of a number of European languages, among which the Balkan Slavic languages figure prominently. The question as to whether clitics are to be located in the syntax or in the phonology or in both is addressed in articles by Boškovič, Progovac and Franks, who also provides a thorough introductory essay to the volume. There are detailed studies on clitic behavior in Greek relative clauses (Alexiadou and Anagnostopolou), Bulgarian and English DPs (Dimitrova-Vulchanova), the various Romance languages (Franco), Slovene (Golden and Milojevič Sheppard), Albanian and Greek (Kallulli) and Macedonian (Tomič). Finally, the book contains a discourse-related description of clitic doubling in Balkan Slavic languages (Schick). The book should be of interest to any scholar, theoretical or descriptive, whose research touches upon the central phenomenon of cliticisation.
