Some Pulitzer winners (5)
I believe the answer is:
poets
'some pulitzer winners' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for poets that I've seen before include "Burns" , "Estop (anag.)" , "Verse writers" , "Heaney and Muldoon" , "bridges, for example (but extra capital is needed)" .)
