The Availability of Island Evasion Strategies in Fragments

In this paper We argue against the repair-by-ellipsis approach to the contrast between non-contrastive fragments and contrastive fragments in terms of syntactic island constraints and rather argue for the non-isomorphic approaches for island evasion strategies. It is presented that non-isomorphic sources for island evasion strategies can be supplied satisfying the felicitous condition for the discourse if the correlates of remnants stays within the scope of [-definite] feature, but cannot if the correlates of fragments are not located within the scope of [-definite] feature. We propose the generalization that island evasion strategies can be available when the correlate of a fragment is [-definite] or within the [-definite] scope. It will be proved that this generalization provides a successful account for some problematic data. Finally, We conclude that the fragments for which island evasion strategies are available can be derived by PF-movement and ellipsis out of appropriate non-isomorphic sources.
