Bounce off the walls, say (4)
I believe the answer is:
echo
I believe this is a double definition.
'bounce off the walls' is the first definition.
(I've seen this in another clue)
'say' is the second definition.
(I know that say is a more specific form of recite)
(Other definitions for echo that I've seen before include "Close imitation" , "Reflect sound" , "Parrot" , "copy" , "Reproduction" .)
