adv

1. In a tyrannous or despotic manner.

   “He finds out, soon enough for his weal and his bane, that he is stronger than Nature: and right tyrannously and irreverently he lords it over her, clearing, delving, dyking, building, without fear or shame.”

   “1894, Arthur S. Way, Hecuba, lines 282–283, page 211 in The Tragedies of Euripides, Vol. I. Not tyrannously the strong should use their strength, Nor they which prosper think to prosper aye.”
