Italian object clitics can be involved in nonlocal dependencies in the sense that they m u s t / m a y appear on a verbal head of which they are not an argument. Two cases where this situation arises will be discussed: the first is due to the presence of an auxiliary verb and the second is triggered by the presence of a certain class of verbs that allows clitic climbing. | Object clitics and clitic climbing in Italian HPSG grammar Paola Monachesi Tilburg University - CLS ITK Postbus 90153 5000 LE Tilburg Nederland e-mail paola@ 1 Introduction Italian object clitics can be involved in nonlocal dependencies in the sense that they must may appear on a verbal head of which they are not an argument. Two cases where this situation arises will be discussed the first is due to the presence of an auxiliary verb and the second is triggered by the presence of a certain class of verbs that allows clitic climbing. An analysis will be proposed within the framework of Head-driven Phrase Structure Grammar Pollard and Sag 1987 Pollard and Sag 1993 it can be shown that an analysis in terms of nonlocal features and the Nonlocal Feature Principle which is the mechanism provided by HPSG to deal with nonlocal dependencies does not provide a satisfactory account of the phenomenon it is too powerful. An alternative approach will be proposed it is based on the idea that the arguments of a verb which is governed by an auxiliary or clitic climbing trigger verb can be raised to become arguments of the governor by a mechanism that achieves an effect similar to functional composition as developed within the tradition of Categorial Grammar. This approach is able to capture the right generalizations to account for the relevant data and can be easily extended to account for long NP-movement which is another property of clitic climbing trigger verbs. 2 Some linguistic properties of Italian clitics There are arguments similar to the ones proposed by Miller 1992a for French showing that Italian clitics exhibit many properties that make them very similar to inflectional affixes the arguments are mainly based on Zwicky and Pullum 1983 . The coordination criteria proposed by Miller 1992b can also be used to support this position. Italian clitics exhibit a high degree of selection with respect to their host they can only attach to verbs. They present arbitrary gaps .
