"Ash Wednesday" poet (5)
I believe the answer is:
eliot
'ash wednesday poet' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for eliot that I've seen before include "T.S. --, poet" , "Female novelist" , "T.S. or George?" , "Pseudonymous writer" , "Author of Adam Bede, d.1880" .)
