Reason to get minced (6)
I believe the answer is:
ground
I believe this clue is a double definition.
'reason' is the first definition.
(synonyms)
'minced' is the second definition.
(I've seen this before)
'to get' acts as a link.
(Other definitions for ground that I've seen before include "territory" , "Land; reduced to powder" , "The solid surface of the Earth" , "Solid part of the earth's surface" , "what coffee might be" .)
