A speechless player (5)
I believe the answer is:
extra
'player' is the definition.
(I know that extra is a type of player)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for extra that I've seen before include "There's more" , "fortuitous run" , "23 player?" , "Maybe wide" , "Additional, more than expected" .)
