Cut with a pointed whip (5)
I believe the answer is:
slash
This clue could be a double definition.
'cut' is the first definition.
(I know that cut can be written as slash)
'pointed whip' is the second definition.
'slash' can be an answer for 'whip' (thesaurus). I'm not certain of the 'pointed' bit.
'with a' acts as a link.
Can you help me to learn more?
(Other definitions for slash that I've seen before include "Cut crudely" , "Cut as with a sword - /" , "Wee stroke < /" , "Drastically prune" , "Reduce (a price) greatly" .)
