Translation of "substantive case" into Chechen

(grammar) A case of second objects, being a derivation of the comparative case but intended for larger, more substantial objects, and used to join or combine one thing with another. It corresponds roughly to a variation of the accusative case: I understood him (him in the substantive case rather than the accusative, since no action is performed on the object). Languages that use the substantive case include Chechen and Ingush. [..]
