Scene involving centre halves in familiar feud (6)
I believe the answer is:
milieu
'scene' is the definition.
(thesaurus)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for milieu that I've seen before include "Social environment or set of surroundings" , "Environmental condition, surrounding" , "(Social) setting" , "Environment - setting" , "'Surroundings, setting (6)'" .)
