Wife leaving got bigger cut (4)
I believe the answer is:
axed
'cut' is the definition.
(I've seen this in another clue)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for axed that I've seen before include "Felled" , "Fired - cut down" , "Discontinued with hatchet?" , "Abandoned project using chopper" , "Chopped or terminated" .)
