Paunches show courage (4)
I believe the answer is:
guts
This might be a double definition.
'paunches' is the first definition.
The definition and answer can be both body parts as well as being plural nouns.
Maybe there's a link between them I don't understand?
'courage' is the second definition.
(I've seen this before)
'show' is the link.
Can you help me to learn more?
(Other definitions for guts that I've seen before include "Cleans - bottle" , "Pluck - viscera" , "Stomach" , "Intestinal courage?" , "Intestines - courage" .)
