Whips (6)
I believe the answer is:
lashes
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">whips</span>' is the definition.<br/ ><span class="explanation-format__explanation">('lash' can be a synonym of 'whip')</span><br/ ><br/ >This is all the clue.<br/ ></span>
(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" .)
