Dice toss (4)
I believe the answer is:
roll
'dice toss' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for roll that I've seen before include "Revolve - piece of bread" , "start a revolution" , "one filled at lunchtime, perhaps" , "Sound of a drum or a list of names" , "movement of ship" .)
