Predicate doubling and parallel chains

This paper discusses predicate fronting with doubling in Russian and Gungbe and argues that it is an instance of parallel chains in the sense of Chomsky (2005). Under this analysis, what superficially looks like a spell out of multiple copies of a single chain turns out to be the instantiation of two simultaneous chains anchored to the same foot. The latter is successfully deleted at PF and only the heads are spelled out, as is normally the case under chain reduction.
