City editor taken in by the French (5)
I believe the answer is:
leeds
'city' is the definition.
(Leeds is an example)
'editor taken in by the french' is the wordplay.
'editor' becomes 'ed'.
'taken in by' indicates putting letters inside.
'the french' becomes 'les' (les is the in french).
'ed' put within 'les' is 'LEEDS'.
(Other definitions for leeds that I've seen before include "W Yorkshire city" , "English city" , "Championship team" , "Yorks city" , "British city and premier division football club" .)
