Dative by Genitive Replacement in the Greek Language of the Papyri: A Diachronic Account of Case Semantics

Semantic analysis of the prenominal first person singular genitive pronoun (μου) in the Greek of the documentary papyri shows that the pronoun is typically found in the position between a verbal form and an alienable possessum which functions as the patient of the predicate. When the event expressed by the predicate is patient-affecting, the possessor is indirectly also affected. Hence the semantic role of this affected alienable possessor might be interpreted as a benefactive or malefactive in genitive possession constructions. By semantic extension the meaning of the genitive case in this position is extended into goal-oriented roles, such as addressee and recipient, which are commonly denoted by the dative case in Ancient Greek. The semantic similarity of the genitive and dative cases in these constructions might have provided the basis for the merger of the cases in the Greek language.
