The syntax of predicate ellipsis in Italian Sign Language (LIS)

We analyze a hitherto undescribed case of ellipsis in Italian Sign Language (LIS) and show that it has common properties with VP ellipsis in languages like English. For example, the ellipsis site can contain a wh-trace and semantic restrictions on the type of predicate that can be omitted are only derivative. We thus propose a phonological deletion approach for the LIS construction. We also consider the issue of how the content of the ellipsis site is recovered from its linguistic antecedent. We present new arguments for a syntactic identity condition, although a limited number of mismatches between the ellipsis site and its antecedent, notably including vehicle change cases, must be accommodated.
