The Old Persian construction mana krtam was shown to be an active perfect in the form of a possessive construction by Benveniste (1952). But this thesis has been challenged by Skjaevø (1985), who calls this construction neutral as to active/passive dichotomy. I would like to show that Benveniste's thesis is correct and that there exists a passive corresponding to the active mana krtam construction, namely avajata construction.
