Whoever that likes relatives...

In this paper we will deal with some aspects of free relative clauses (FRC) in English, showing that there are certain differences between restrictive relative clauses (RRC) featuring whoever on the one hand and whichever / whatever on the other in terms of both their syntax and their semantics. In particular, we will focus on solving a long-standing puzzle that involves paradigms where the opposite of what the venerable *that-t filter would predict obtains.
