• The present study is concerned with Single Clitics, as weil as with Clitic Doubling and Clitic Left Dislocation constructions and will test the Uniformity Hypothesis (Sportiehe 1992), according to which all three constructions involve the same underlying structure. It will be shown that: - acquisition data pose a problem for the Uniformity Hypothesis (Sportiche 1992) and support rather the idea that Single Clitic, Clitic Doubling and Clitic Left Dislocation constructions do not involve the same underlying structure, - omission of definite articles in Clitic Doubling and Clitic Left Dislocation constructions parallels omission of definite articles in simple DPs, - selective omission of some types of Determiners, i.e. definite articles and use of another type of Determiners, i.e. clitic pronouns, can be explained in terms of the different feature specification of words belonging to the category D and the different status of clitics vs. definite articles.
