Construcciones existenciales en lenguas romances: requisitos y efectos de la inserción de clíticos locativos. Datos del italiano, catalán, francés y español.

The present paper focuses on Italian existential structures and on the incidence of the clitic ci, allegedly locative, in the interpretation of the whole clause predicate, aiming to find out a link between the clitic's presence and the notorious changes in the lexical and syntactic configuration of the base verb. The comparisons made with Catalan, French and Spanish are intended to support such a hypothesis, given that these languages take haber as base verb for existential structures, whose possessive meaning has been confirmed in the first two languages, a value that seems to be subdued in the presence of the element required (hi o y, respectively) in favour of the existential interpretation of constructions such as haver-hi o il y ha.
