Come again possible like the self-centred one (9)
I believe the answer is:
egomaniac
'the self-centred one' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'come again possible' is the wordplay.
'come again' anagrams to 'EGOMANIAC'.
But, I am unsure how the anagram is indicated.
'like' is the link.
Can you help me to learn more?
(Other definitions for egomaniac that I've seen before include "who's full of himself" , "Self-obsessed person" , "he thinks "it's all about ME"" , "Excessively self-absorbed person" , "Bighead" .)
