Harsh, authoritarian (10)
I believe the answer is:
oppressive
I believe this is a double definition.
'harsh' is the first definition.
(thesaurus)
'authoritarian' is the second definition.
(thesaurus)
(Other definitions for oppressive that I've seen before include "Sultry" , "Difficult to bear" , "cruel" , "overpowering!" , "Tyrannical" .)
