Say your piece? (6)
I believe the answer is:
recite
'say' is the definition.
(I know that say is a kind of recite)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for recite that I've seen before include "Declaim aloud" , "Repeat aloud from memory as for audience" , "Reel off" , "Declaim, recount" , "Intone" .)
