Passive and impersonal reflexives in the Italian dialects: synchronic and diachronic aspects (Plenary talk)

• Analysis of the morphosyntax of passive and impersonal reflexives in contemporary Italian dialects and in some XI-XIV century northern (O.Venetian and O.Lombard), central (O. Florentine) and southern (O. Neapolitan and O. Logudorese Sardinian) vernaculars. • Investigation of some parameters of variation in the use of passive and impersonal reflexives in Italo-Romance, both synchronically and diachronically: (i) the functional domains covered by the reflexive morpheme, (ii) the morphological and/or syntactic distinction between passive and impersonal reflexives, (iii) the nature of the subject, (iv) tense-aspectual restrictions, (v) the interplay of generic vs specific time reference with differential behaviour of transitive-unergatives vs unaccusatives, in determining the occurrence/lack of the reflexive in impersonal function in perfective contexts.
