Perform at a poetry slam (6)
I believe the answer is:
recite
'perform at a poetry slam' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for recite that I've seen before include "Repeat verbatim" , "Repeatr aloud from memory" , "Speak (eg, a poem)" , "Declaim aloud" , "Intone" .)
