Clitici e slittamento accentuale nelle varietà sarde: tra prosodia e allomorfia

Sardinian varieties display stress shifts under cliticization with imperative and gerund verb forms. Stress placement is related to the type and number of clitics associated to the verbal host. Up to three enclitics are acceptable. They can be clitic personal pronouns, as well as locative and partitive clitics. From a typological point of view, three different stress shift patterns are attested in Sardinian varieties. The first one is from Campidanese Sardinian, the second one from Logudorese-Nuorese Sardinian, whereas the last one is from the transitional area between Logudorese-Nuorese and Campidanese Sardinian. In the case of clitic clusters, all Sardinian varieties act in the same way: stress shifts to the penultimate syllable of the host + clitic(s) sequence. A good degree of variation is available in the case of adjunction of a single clitic. Thus, while in Logudorese-Nuorese Sardinian, a single clitic has no effect on the stress of its verbal host, the other Sardinian varieties display two different stress shift patterns. In Campidanese Sardinian, the stress shifts to the final syllable of the sequence with 1st and 2nd person clitic pronouns, while with 3rd person clitics (non-reflexive) and partitive and locative clitics, the stress is placed on the penultimate syllable. In the transitional area, single clitics (of any category) cause the same stress shift placement as in the case of clitic clusters (to the penultimate syllable). All combinations of clitics will be taken into account in order to determine the conditions under which a stress shift may be observed across Sardinian varieties.
