City accountant, male needing some dental work (9)
I believe the answer is:
cambridge
'city' is the definition.
(Cambridge is an example)
'accountant male needing some dental work' is the wordplay.
'accountant' becomes 'ca' (abbreviation for chartered accountant).
'male' becomes 'm' (common abbreviation).
'needing' is a charade indicator (letters next to each other).
'some dental work' becomes 'bridge' (I can't explain this - if you can you should believe this answer much more).
'ca'+'m'+'bridge'='CAMBRIDGE'
Can you help me to learn more?
(Other definitions for cambridge that I've seen before include "Light blue university?" , "East Anglian city" , "English city" , "Old English university" , "place of learning" .)
