Stress shift, stressed enclitics and Raddoppiamento Sintattico in Southern Italian dialects
Résumé
In Southern Italian dialects we find several verbal forms which show double enclitics Cl1Cl2, where we observe a stress shift on Cl1 or on final verbal V before a Cl. In these Italian varieties this has consequences for the rule of Raddoppiamento Sintattico since a geminate of the first consonant is triggered in such clitics: after the stress shift, any initial consonant of Cl can geminate. The geminate in clitics is conditioned by the constraint STRESS-TO-WEIGHT (STW). In Italian (and in Spanish but not in Catalan) the stress is not shifted on clitics in parallel forms.
The stress shift in Italo-Romance dialects follow what I call the three-moras-window and pronominal postverbal enclitics always behave as phonological words footed with the verbs. In these verbal structures stress fells on one of the last three moras which identify the maximal prosodic window (see also Spagnoletti & Dominicy 1992; Loporcaro 2000; Gerlach 2002). Stress shift takes place on clitics clusters to avoid the stress to fall on the fourth mora. This analysis is presented in a version of OT (Kager 1999; 2012; McCarthy & Prince 1993 and following works; Rosenthal & Hulst 1999; Gordon 2004) joined with prosodic and metrical phonology (Selkirk 1992; 1995; Hayes 1995; Peperkamp 1995; 1996; 1997a/b; Anderson 2011; Itô & Mester 2009).
