Self-centred, lunatic rebels come again (9)
I believe the answer is:
egomaniac
'self-centred lunatic' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'rebels come again' is the wordplay.
'rebels' is an anagram indicator.
'come'+'again'='comeagain'
'comeagain' with letters rearranged gives 'EGOMANIAC'.
Can you help me to learn more?
(Other definitions for egomaniac that I've seen before include "Oneself, one would love" , "One who's self-obsessed" , "Excessively self-concerned person" , "Come again (anag.)" , "Highly self-absorbed person" .)
