Estate managed by church (5)
I believe the answer is:
ranch
'estate' is the definition.
(thesaurus)
'managed by church' is the wordplay.
'managed' becomes 'ran' (I've seen this before).
'by' says to put letters next to each other.
'church' becomes 'ch' (common abbreviation**).
'ran'+'ch'='RANCH'
(Other definitions for ranch that I've seen before include "Agricultural business" , "Large US cattle farm" , "Stock farm in US, Aus." , "Spread" , "Agricultural establishment" .)
