Type-Restricted Argument Ellipsis and Generalized Quantifiers

Theories of argument ellipsis based on PF deletion or LF copying do not generate predictions regarding possible constraints on the semantic type of the elided argument. Yet such constraints obtain, as documented in Landau 2022: only type-e arguments can be targeted by argument ellipsis. Focusing on quantificational arguments here, I show that when they yield readings expressible by type-e denotations, they may elide, but when they denote genuine generalized quantifiers, they may not. Utilizing the restricted range of interpretations made available by choice function binding and E-type pronouns, the analysis derives a number of peculiar scopal properties of indefinite NPs, quantifiers, and exceptive phrases under argument ellipsis.
