Force new church to accept tradition in city (8)
I believe the answer is:
florence
'city' is the definition.
(I know that Florence is a city)
'force new church to accept tradition' is the wordplay.
'force' becomes 'f' (scientific abbreviation).
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'church' becomes 'CE' (Church of England).
'to accept' means one lot of letters goes inside another.
'tradition' becomes 'lore' (I've seen this in other clues).
'f'+'n'+'ce'='fnce'
'fnce' going around 'lore' is 'FLORENCE'.
'in' is the link.
(Other definitions for florence that I've seen before include "Italian city, home of the Uffizi Gallery" , "Ms Nightingale in great Italian city" , "Name of girl ? city" , "City on R. Arno" , "Angel of the reclining (anag) -- nurse" .)
