Is absorbed by medal - time to show guts (7)
I believe the answer is:
viscera
'guts' is the definition.
(viscera are one's internal organs)
'is absorbed by medal time' is the wordplay.
'absorbed by' indicates putting letters inside.
'medal' becomes 'VC' (Victoria Cross, military medal).
'time' becomes 'era' (era is a kind of time).
'is' placed into 'vc' is 'visc'.
'visc'+'era'='VISCERA'
'to show' acts as a link.
(Other definitions for viscera that I've seen before include "Abdominal organs -- cars vie (anag)" , "Internal organs, intestines" , "Entrails -- CIS rave (anag)" , "Guts" , "organs inside" .)
