Given copper plating, detest a castle
I believe the answer is:
chateau
'castle' is the definition.
(thesaurus)
'given copper plating detest a' is the wordplay.
'given copper' becomes 'cu' (chemical symbol. I am not sure about the 'given' bit.**).
'plating' indicates putting letters inside (I've seen this in other clues).
'detest' becomes 'hate' ('hate' can be a synonym of 'detest').
'hate'+'a'='hatea'
'cu' enclosing 'hatea' is 'CHATEAU'.
Can you help me to learn more?
(Other definitions for chateau that I've seen before include "Kind of fine wine from the Bordeaux region" , "Impressive house in France" , "Loire Valley attraction" , "Vineyard estate around Bordeaux" , "Impressive French building" .)
