Link royal backstory to headless lion (8)
I believe the answer is:
relation
'link' is the definition.
(I've seen this in another clue)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for relation that I've seen before include "Respect" , "Connection; narrative" , "Mum or dad" , "Story; member of family" , "wife?" .)
