Around noon, what farmer's wife hated to chop up (5)
I believe the answer is:
mince
'chop up' is the definition.
(mincing is a kind of chopping up)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for mince that I've seen before include "Cut fine" , "Chop into small pieces" , "Grind up (meat)" , "getting chop" , "Grind (food)" .)
