Poet of golden study (5)
I believe the answer is:
auden
'poet' is the definition.
(WH Auden, 1907-1973)
'golden study' is the wordplay.
'golden' becomes 'au' (Au is the chemical symbol for gold).
'study' becomes 'den' (term for a study or office).
'au'+'den'='AUDEN'
'of' acts as a link.
(Other definitions for auden that I've seen before include "W. H. - , UK/US poet" , "British-born American poet" , "British-born writer" , "W. H. -, English poet" , "Wystan Hugh -, poet" .)
