Disperses (8)
I believe the answer is:
scatters
'disperses' is the definition.
('scatter' can be a synonym of 'disperse')
This is all the clue.
(Other definitions for scatters that I've seen before include "Throws in random directions" , "Disperses in all directions" , "Disperses or strews" , "Disperses and throws around" , "Strews in all directions" .)
