Deconstructing SE-Constructions: number agreement and postsyntactic variation

Abstract

Most analyses of nonparadigmatic SE sentences derive their agreement patterns structurally, forcing a passive/impersonal distinction against all evidence. Instead, we uniformly analyze them as regular sentences where the T-agreeing subject is se itself, an argumental clitic pronoun, with [person] but no number features, and show that the overt argument, which has object properties, does not genuinely agree in syntax. We reveal a new asymmetry between postverbal and preverbal/null arguments, which conceals two postsyntactic processes with very distinctive properties: morphological Clitic Mutation into number agreement, and T’s Number Harmony with a close DP, not ruled by syntax or morphology.
