Speechless player (5)
I believe the answer is:
extra
This clue could be a double definition.
'speechless' is the first definition.
Both the answer and definition are adjectives. Maybe there's a link between them I don't understand?
'player' is the second definition.
(I know that extra is a type of player)
Can you help me to learn more?
(Other definitions for extra that I've seen before include "non-standard item" , "like one of the crowd" , "Minor actors in crowd scenes" , "Taxer (anag.)" , "No great contribution to film" .)
