Survivor of butchering? (5)
I believe the answer is:
liver
'survivor of butchering?' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps there's an association between them I don't understand?
This is the entire clue.
Can you help me to learn more?
(Other definitions for liver that I've seen before include "Part of body" , "Glandular organ in the abdomen" , "Large organ in the abdomen secreting bile" , "Bile-secreting gland" , "Large gland" .)
