Universal 14: verb agreement with case-less objects ⇒ verb agreement with case-marked objects
Original
If verbs agree with objects, they are likelier to do so with case marked than case-less ones. OR There is no language, given that it has a class of direct objects including both members that are case-marked and also members that are not case-marked, where the verb agrees with some or all of those not case-marked but with none of those case-marked.
Standardized
IF verbs agree with objects when they are not marked for case, THEN they will also agree with the same objects when they are marked for case.
