oa V-stranding ellipsis and verbal identity: The role of polarity focus

This paper shows that the identity condition that characterizes V-stranding ellipsis is not verbal and does not only characterize syntactic heads. In some contexts, this type of ellipsis can strand phrasal material distinct from verbs that complies with the identity condition. The kind of contexts in which this can be attested are contexts in which ellipsis elides a TP licensed by a polarity focus head Σ0. This finding has important theoretical consequences for the explanation of the identity condition in V-stranding ellipsis, as it cannot be captured by current theories that put down identity to the special status of head movement in grammar.
