ABSTRACT
In this article I examine a number of phenomena, each representing a seemingly distinct restriction on Ā-chain formation. Some of these phenomena have not yet been explained. Others have been analyzed in different ways. Where relevant, I will discuss previous analyses and note potential problems with them. So far no analysis has provided a unified explanation for these restrictions. I will demonstrate that Chomsky’s ( 1991 ) Economy Constraint, a constraint motivated on entirely independent grounds, does just that. In the course of the discussion I will also examine the Earliness Principle, a derivational constraint proposed by Pesetsky (1989) as a replacement for the Economy Constraint.
