Swell way to ask Gatsby to visit? (8)
I believe the answer is:
popinjay
'swell way to ask' is the definition.
I can't judge whether this defines the answer.
'gatsby to visit?' is the wordplay.
'gatsby' becomes 'jay' (I've seen this in another clue).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'visit?' becomes 'popin' (I am not sure about this - if you are sure you should believe this answer much more).
'jay' put after 'popin' is 'POPINJAY'.
Can you help me to learn more?
(Other definitions for popinjay that I've seen before include "Foppish type" , "One super-smart" , "vain sort" , "Conceited person" , "Strutting fop" .)
