Cyclic Expansion in Agree: Maximal Projections as Probes

Abstract

When we couple the cyclic expansion of a probe’s domain assumed in Cyclic Agree (Rezac 2003, 2004, Béjar and Rezac 2009) with the lack of formal distinction between heads, intermediate projections, and phrases emphasized in Bare Phrase Structure (Chomsky 1995a,b), an interesting prediction arises. Maximal projections should be able to probe through the same mechanisms that allow intermediate projections to probe in familiar cases of Cyclic Agree. I argue that this prediction is borne out. I analyze agreeing adjunct C in Amahuaca (Panoan; Peru) as a maximal projection that probes its c-command domain in second-cycle Agree. This account derives C’s simultaneous sensitivity to DPs within its own clause and in the clause to which it adjoins. Therefore, I conclude that Amahuaca provides evidence that maximal projections can be probes. The account also yields insight into the syntax of switch-reference in Panoan and beyond.
