University opens a study for poet (5)
I believe the answer is:
auden
'poet' is the definition.
(Auden is an example)
'university opens a study' is the wordplay.
'university' becomes 'u'.
'opens' indicates putting letters inside (one set of letters makes an 'opening' in another).
'study' becomes 'den' (I've seen this before).
'a'+'den'='aden'
'u' inserted within 'aden' is 'AUDEN'.
'for' is the link.
(Other definitions for auden that I've seen before include "W. H. -, English-born poet" , "W. H. -, English poet" , "British-born writer" , "W. H. -, Eng. poet" , "20th-century Anglo-American poet" .)
