City not good for verbose academic (6)
I believe the answer is:
london
'city' is the definition.
(I know that London is a city)
'not good for verbose academic' is the wordplay.
I cannot quite see how this works, but
'not' could be 'o' (I've seen this in other clues) and 'o' is found within the answer.
'academic' could be 'don' (type of academic - especially at Oxbridge) and 'don' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for london that I've seen before include "- Clay; - pride; - plane" , "City of the Cockneys" , "UK's capital" , "English capital" , "UK Capital city" .)
