Chop crudely (4)
I believe the answer is:
hack
'chop crudely' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for hack that I've seen before include "try to access unauthorised data" , "jade" , "Wildly kick; dull writer" , "Tired old horse" , "get information illegally" .)
