Diachronic change and pronoun status: Italian dative loro

Abstract

From a historical perspective, personal pronouns in Romance languages display a tendency to undergo changes in syntactic status in a particular order, namely; strong > weak > clitic. This paper discusses the possible reasons behind the final step of this sequence of development, i.e. that from a weak form to clitic status. It will be argued that the external trigger for this kind of diachronic change has to be a morphophonological one; if a weak pronoun is morphophonologically reduced over time, language learners may at some point come to analyse the pronoun as a clitic. A number of syntactic properties are expected to change as a consequence of the switch from weak form to clitic. This view gives support to Cardinaletti & Starke’s (1999) approach which argues for a principled link between the morphophonological make-up of pronouns and their syntactic status. Furthermore, it is shown that the Italian dative pronoun loro ‘to-them’ during the 13th and 14th centuries underwent changes that corroborate the above hypothesis in an interesting way. Originally, loro was a weak pronoun but in some central Italian varieties, above all in the town of Siena, a reduced form lo’ emerged, which had clitic properties. Arguably, the phonological change preceded the syntactic one. For a period, both loro and lo’ are attested in rather free distribution. Later on however, the Sienese grammar makes a clear distinction between them, analysing lo’ as a dative clitic and loro as a strong pronoun. (Less)
