"Endymion” poet (5)
I believe the answer is:
keats
'endymion poet' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for keats that I've seen before include "Endymion, Lamia poet" , "English romantic poet, d. 1821" , "English poet, 1795-1821" , "Author of Endymion and Ode to a Nightingale" , "Ode to Autumn poet" .)
