Distinguished singer keen to make comeback (4)
I believe the answer is:
diva
'distinguished singer' is the definition.
'diva' can be an answer for 'singer' (diva is a kind of singer). I'm unsure of the 'distinguished' bit.
'keen to make comeback' is the wordplay.
'keen' becomes 'avid' (I've seen this before).
'to make comeback' shows that the letters should be reversed in order (I've seen 'making comeback' mean this).
'avid' reversed gives 'DIVA'.
Can you help me to learn more?
(Other definitions for diva that I've seen before include "High-maintenance opera singer?" , "Great performer" , "Prima dona" , "Prima donna, woman opera singer" , "High-maintenace woman" .)
