Play charades (4)
I believe the answer is:
mime
'play charades' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for mime that I've seen before include "Job progress" , "Act without words, like Marcel Marceau (4)" , "Marcel Marceau's art" , "Pretend to sing" , "Play without dialogue" .)
