Canceled abruptly (4)
I believe the answer is:
axed
'canceled abruptly' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for axed that I've seen before include "Abandoned project using chopper" , "Cancelled or dismissed suddenly" , "Dismissed with a hatchet" , "Felled" , "Abandoned or curtailed - using hatchet?" .)
