One who wrote poetry from a university hideaway (5)
I believe the answer is:
auden
'one who wrote poetry' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'a university hideaway' is the wordplay.
'university' becomes 'U' (abbreviation for university).
'hideaway' becomes 'den' (synonyms).
'a'+'u'+'den'='AUDEN'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for auden that I've seen before include "US poet born in Britain" , "British-born writer" , "Wystan Hugh -, poet" , "W. H. ... (British poet)" , "W. H. -, Eng. poet" .)
