Gentle, submissive (4)
I believe the answer is:
meek
I believe this is a double definition.
'gentle' is the first definition.
(thesaurus)
'submissive' is the second definition.
(I've seen this before)
(Other definitions for meek that I've seen before include "Mild and gentle" , "Gentle and submissive" , "one who inherits?" , "Patient and easily imposed upon" , "Humble and obedient" .)
