Phonological correlates of syntactic structure. The distribution of raddoppiamento fonosintattico in Calabrian

The present article considers the syntactic constraints operative on the distribution of a phonological fortition process, raddoppiamento fonosintattico 'phonosyntactic doubling', in the Calabrian dialect of Cosenza. It is shown that the relevant locality restrictions are best understood, not in terms of the three core structural configurations Spec-Head, Head-Head and Head-Comp, but in terms of phasal domains, highlighting how different phonological realizations represent the spell-out of deep syntactic differences mapped at the syntax-phonology interface. At the same time, the theoretical assumptions assumed here provide us with the key to understanding some intriguing empirical generalizations about the distribution of Cosentino RF which, in turn, throw new light on some current theoretical assumptions about clause structure and the nature of phases.
