This paper explores multiple wh-fronting under Sluicing. Contrary to previous proposals that an interrogative +wh complementizer licenses TP-ellipsis, I propose that +focus feature licenses this ellipsis operation. Assuming the deletion analysis of sluicing, following Ross (1969), I argue for focus-licensed sluicing based on data from Slavic languages like Russian and Polish, where it is possible to have focused R-expressions as remnants of sluicing. I demonstrate how semantic restrictions in multiple interrogatives are maintained under sluicing, presenting a new argument for the clausal structure of the sluice. Finally, I explore Superiority effects under sluicing, deriving those from parallelism in variable binding.
