Case transmission in Classical Latin control structures: Between syntax and morphology

Latin nonfinite structures with nonovert subjects exhibit puzzling properties regard to the case- and ϕ-features of their relationship overt NPs in matrix clauses. While transmission ϕ-feature related is obligatory when there a nominative or accusative controller NP, it only that remains dative controller, case being apparently optional. To avoid an assumption syntactic optionality, accounts phenomenon which rely on mechanisms propose apparent optionality reflects difference between two types structures. It instead proposed linking objects via Agree should be assigned different components grammar, syntax morphology. The hypothesis allows unified treatment control Latin.
