Social surroundings (6)
I believe the answer is:
milieu
'social surroundings' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for milieu that I've seen before include "Social environment or set of surroundings" , "'Surroundings, setting (6)'" , "Environment - setting" , "(Social) setting" , "Surroundings - location" .)
