Visit judge, ever the foppish fellow (8)
I believe the answer is:
popinjay
'fellow' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for popinjay that I've seen before include "vain sort" , "Coxcomb" , "Conceited person" , "Strutting fop" , "Foppish type" .)
