Whips (6)
I believe the answer is:
lashes
'whips' is the definition.
('lash' can be a synonym of 'whip')
This is all the clue.
(Other definitions for lashes that I've seen before include "Strikes with a whip" , "Blows delivered with a whip" , "Eyeshades for punishments" , "Punitive strokes of a whip" , "on the lid" .)
