An Italian poet here could make quite a slow movement (5)
I believe the answer is:
dante
'an italian poet' is the definition.
(Dante Alighieri)
'here could make quite a slow movement' is the wordplay.
I cannot really understand how this works, but
'a' could be 'an' and 'an' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for dante that I've seen before include "Finally stand before" , "Thirteenth-fourteenth century Italian poet" , "Italian poet, 1265-1321" , "Net Da a poet" , "Inferno poet" .)
