Predicate fronting with verb doubling in Krachi: A parallel chains analysis
This article examines verb doubling predicate focus constructions in Krachi, an endangered language of Ghana. Krachi has three such constructions: one where V alone appears in the left periphery; another where VO has been fronted; and a third involving OV inversion in the fronted constituent. Regardless of the fronted expression, the constructions can be interpreted either contrastively or exhaustively. We argue that all three constructions involve the same mechanism – the formation of parallel chains anchored to the same syntactic object. We propose that the parallel chains formed in all three cases are identical, involving one v0-to-T0 head movement chain and one v’-to-Spec, FocP A-bar chain. The reduction of these chains at PF yields the surface doubling of the predicate without appeal to multiple copy spell-out. We propose that minor differences in the PF interpretation of the peripheral v’ copy account for the differences in word order between the three constructions.
