Masters of allusion? (5)
I believe the answer is:
poets
'masters of allusion?' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for poets that I've seen before include "Estop (anag.)" , "Verse writers" , "bridges, for example (but extra capital is needed)" , "Heaney and Muldoon" , "Burns" .)
