Fabulous Greek geezer who's a bit of a nag in part (7)
I believe the answer is:
centaur
'fabulous greek geezer' 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?
'a bit of a nag in part' is the wordplay.
I cannot quite see how this works, but
'a' is found in the answer.
'in part' could be 'en' ('en' is part of 'in') and 'en' is found within the answer.
This explanation may well be incorrect...
'who's' is the link.
Can you help me to learn more?
(Other definitions for centaur that I've seen before include "Mythological creature" , "Mythical hybrid" , "Mythical animal, half man and half horse" , "Mythical creature, half-man, half-horse" , "Fabulous horse-man" .)
