Context; upbringing (10)
I believe the answer is:
background
I believe this is a double definition.
'context' is the first definition.
(thesaurus)
'upbringing' is the second definition.
(thesaurus)
(Other definitions for background that I've seen before include "player's obscure position" , "history" , "Reason behind" , "Environment" , "Unobtrusive element" .)
