This book contains fourteen articles that reflect current ideas on the phonology, morphology, and syntax of clitics. It covers the forms and functions of clitics in various typologically diverse languages and presents data from, e.g. European Portuguese, Macedonian, and Yoruba. It extensively deals with the prosodic structure of clitics, their morphological status, clitic placement, and clitic doubling. The form and behavior of clitics with respect to tonal phenomena and in verse are discussed in two articles (Akinlabi & Liberman, Reindl & Franks). Other articles address the prosodic representation of clitics in Irish (Green), the differences in the acquisition of clitics and strong pronouns in Catalan (Escobar & Gavarro), the similarities between clitics and affixes or words in Romance and Bantu languages (Cocchi, Crysmann, Monachesi, Ortman & Popescu), the semantics of clitics in the Greek DP and in Spanish doubling (Alexiadou & Stavrou, Uriagereka), and complex problems concerning verbal clitics in Romanian and Balkan languages (Legendre, Spencer, Tomic).
