"Clitics" presents a prosodic treatment of clitics and cliticization, using an integrated approach involving Lexical Phonology, Prosodic Phonology, and Optimality Theory. Taking the prosodic properties of clitics as a starting point, a proposal is made for the prosodic representation of clitics. An analysis of the differences between clitics and affixes is presented, leading to the claim that clitics constitute a subset of postlexical affixes. Hence, cliticization is considered to be an instantiation of postlexical affixation. Data are drawn from a variety of languages, including detailed case-studies on the noteworthy systems of Pashto, uiotepec Chinantec, and European Portuguese. As the book provides an integration of several phonological theories on the one hand, and deals with the phonology-morphology interface on the other hand, "Clitics" is of interest to theoretical phonologists working in the fields of Lexical Phonology, Prosodic Phonology, Optimality Theory, and Morphology, and for anyone else interested in clitics.
