Writers cornered in Westminster Abbey (5)
I believe the answer is:
poets
'writers' is the definition.
(poet is a kind of writer)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for poets that I've seen before include "Heaney and Muldoon" , "Estop (anag.)" , "Burns" , "bridges, for example (but extra capital is needed)" , "Verse writers" .)
