Tame, obedient (6)
I believe the answer is:
docile
I believe this is a double definition.
'tame' is the first definition.
(similar in meaning)
'obedient' is the second definition.
(similar in meaning)
(Other definitions for docile that I've seen before include "Gentle and biddable" , "Gentle and teachable" , "Quiet, willing to obey" , "Manageable" , "Willing to be taught or led" .)
