Peacock: it goes flying around (6)
I believe the answer is:
egoist
'peacock' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'it goes flying around' is the wordplay.
'flying around' indicates anagramming the letters.
'it'+'goes'='itgoes'
'itgoes' anagrammed gives 'EGOIST'.
Can you help me to learn more?
(Other definitions for egoist that I've seen before include "Selfish type" , "Conceited person with little regard for others" , "Bighead" , "self-seeking type" , "Selfish person" .)
