Abstract:  We suggest that the singular pronoun it has split antecedents in the discourse Mary will bake a strudel or John will buy a tiramisù. I will devour it. Specifically, we argue that this analyis is obtained 'for free' from the combination of (i) the mechanism that allows plurals to have split antecedents, together with (ii) a treatment of NPs as introducing discourse referents with maximality conditions (as is standard in recent dynamic accounts).
