Modal cumulativity
Sentences containing two or more plural expressions are known to allow cumulative readings (Kroch 1974, Scha 1981 a.o.). For instance, "the boys fed the dogs" has a reading that says that each boy fed at least one dog, and each dog was fed by at least one boy. We observe instances of cumulativity involving expressions that create intensional environments, such as conditionals and modals. For instance, "If these three professors come to my talk, I’ll be very nervous" has a weak reading that says that I'll be nervous in case one of these three professors comes. We take this to indicate that the conditional expression "if" can participate in cumulation, specifically, with the plural subject "these three professors" in the antecedent proposition in this example. To account for this observation, we mainly explore two theoretical options: the operator approach (Beck and Sauerland 2002) and the plural projection approach (Schmitt 2019) to cumulativity. We conclude that both approaches can capture modal cumulativity with the assumption of plural possible worlds (contra Schmitt 2023, who argues that plural worlds do not exist).
