"The Fiddler of Dooney" poet (5)
I believe the answer is:
yeats
'the fiddler of dooney poet' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for yeats that I've seen before include "W.B. - (Irish poet)" , "Irish poet and dramatist, d. 1939" , "he wrote" , "Irish poet, 1923 Nobel Prize winner" , "William Butler .. . . ., Nobel-winning poet" .)
