Western shire perhaps taking over for each area (5,5)
I believe the answer is:
horse opera
'western' is the definition.
('horse opera' can be a synonym of 'western')
'shire perhaps taking over for each area' is the wordplay.
'shire perhaps' becomes 'horse' (shire is a kind of horse).
'taking' says to put letters next to each other.
'over' becomes 'o' (cricket abbreviation**).
'for each' becomes 'per' (I've seen this before).
'area' becomes 'a' (maths abbreviation).
'horse'+'o'+'per'+'a'='HORSE OPERA'
(Another definition for horse opera that I've seen is " Western".)
