Poet requiring a university study (5)
I believe the answer is:
auden
'poet' is the definition.
(WH Auden, 1907-1973)
'a university study' is the wordplay.
'university' becomes 'U' (abbreviation for university).
'study' becomes 'den' (term for a study or office).
'a'+'u'+'den'='AUDEN'
'requiring' acts as a link.
(Other definitions for auden that I've seen before include "W. H. - , UK/US poet" , "W.H. --, English poet" , "US poet born in Britain" , "W. H. -, Eng. poet" , "Wystan Hugh -, poet" .)
