Floating quantifiers in Japanese passives and beyond

Abstract This work attempts to defend the so-called Uniform Hypothesis for passives in Japanese by re-examining the empirical phenomena involving quantifier float (Q-float). We will attempt to reinforce the following main tenets of the Uniform Hypothesis — (i) that all ni-passive sentences in Japanese involve complementation and the theta-marking of their subjects, and (ii) that they crucially lack NP movement. We will also closely examine the syntactic, semantic, pragmatic and prosodic properties of Q-float in general.
