Nobel-winning poet Heaney (6)
I believe the answer is:
seamus
'nobel-winning poet heaney' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for seamus that I've seen before include "Irish form of James" , "Irish poet, b. 1939" , "- Heaney, Irish poet" , "Irishman?" .)
