English country manor (6)
I believe the answer is:
estate
'manor' is the definition.
(thesaurus)
'english country' is the wordplay.
'english' becomes 'e' (abbreviation).
'country' becomes 'state' ('state' can be a synonym of 'country').
'e'+'state'='ESTATE'
(Other definitions for estate that I've seen before include "What you leave when you die" , "One car" , "All of one's assets -- 5-door car" , "Nakedness" , "Tea-set (anag.)" .)
