Original: If there is a construction in which the verb agrees with some member of the relational hierarchy Subject > DO > IO > Oblique > [Genitive], then there are at least some constructions in which the verb agrees with members higher on that hierarchy .
Standardized: IF the verb agrees with Attributive, THEN it also agrees with Oblique Object.
IF the verb agrees with Oblique Object, THEN it also agrees with Indirect Object.
IF the verb agrees with Indirect Object, THEN it also agrees with Direct Object.
IF the verb agrees with Direct Object, THEN it also agrees with Subject.
