"Frost at Midnight" poet (9)
I believe the answer is:
coleridge
'frost at midnight poet' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for coleridge that I've seen before include "Exponent of art" , "Kubla Khan poet" , "Samuel Taylor . . . . . . . . ., eminent poet" , "Samuel Taylor . . . . . . . . . who wrote 'The Ancient Mariner'" , "English poet" .)
