"The Age of Anxiety" poet (5)
I believe the answer is:
auden
'the age of anxiety poet' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for auden that I've seen before include "W. H. -, English-born poet" , "W. H. -, Eng. poet" , "20th-century Anglo-American poet" , "British-born American poet" , "W. H. - , UK/US poet" .)
