Move like a ball (4)
I believe the answer is:
roll
'move like a ball' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for roll that I've seen before include "Drumming pattern" , "Eg, bap" , "Throw (a die or dice)" , "on which one is regularly successful" , "Sound of a drum or a list of names" .)
