Church primate wants gold hat (7)
I believe the answer is:
chapeau
'hat' is the definition.
(synonyms)
'church primate wants gold' is the wordplay.
'church' becomes 'ch' (abbreviation on maps etc).
'primate' becomes 'ape' (large primate).
'wants' says to put letters next to each other.
'gold' becomes 'Au' (Au is the chemical symbol for gold).
'ch'+'ape'+'au'='CHAPEAU'
(Other definitions for chapeau that I've seen before include "something to put on noodles" , "Fashionable hat" , "Cap (French or heraldic?)" , "(French) hat" .)
