Narcissist keen to make a comeback (4)
I believe the answer is:
diva
'narcissist' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'keen to make a comeback' is the wordplay.
'keen' becomes 'avid' (I've seen this before).
'to make a comeback' shows that the letters should be reversed in order (I've seen 'making a comeback' mean this).
'avid' written backwards gives 'DIVA'.
Can you help me to learn more?
(Other definitions for diva that I've seen before include "Operatic soprano" , "Prima dona" , "Distinguished female singer" , "Callas, say" , "Celebrated female operatic star" .)
