Challenging Clitics deals with multiple sides of cliticisation from different theoretical frameworks and with data from a number of different languages. Unlike many other books on clitics where clitics are considered from a mere syntactical point of view, this book also discusses the acquisition of clitics; the role of the PF in cliticisation; the morphophonological aspects of cliticisation; and historical change - to name but a few of the approaches presented. As such this collection presents cutting edge theoretical considerations as well as new data on clitics. Taken together, the contributions in this volume not only provide insight into the extremely complex nature of clitics, but also into derivations and structures in language that go beyond the study of clitics themselves.
