- The paper deals with a long-standing problem of Slavic Historical Linguistics, which is the question why in the history of Old East Slavic (OESl) there occurred a substitution of the Adjective by the Genitive case of a noun as a means of expressing possession. The main postulate is that there existed a previously unnoticed connection between this substitution, on the one hand, and the rise of a new syncretic Accusative case form, known as Genitive-Accusative, on the other. It is suggested that the missing link underlying both processes is the intolerance of the language to Subject-Object ambiguity.
