For city new galleons are French (3,7)
I believe the answer is:
los angeles
'for city' is the definition.
(Los Angeles is an example)
'new galleons are french' is the wordplay.
'new' is an anagram indicator.
'are french' becomes 'es' ('are' in French).
'galleons' anagrammed gives 'losangel'.
'losangel'+'es'='LOS ANGELES'
(Other definitions for los angeles that I've seen before include "Second most populous city in the US" , "LA, California" , "centre of population" , "city on Pacific" , "city abroad" .)
