Humble subject (7)
I believe the answer is:
conquer
I believe this is a double definition.
'humble' is the first definition.
(thesaurus)
'subject' is the second definition.
(thesaurus)
(Other definitions for conquer that I've seen before include "worst" , "Capture by force" , "Put down by force" , "Defeat, overcome" , "Gain possession by force" .)
