Girl from French city undermining continental community (6)
I believe the answer is:
eunice
'girl' is the definition.
'french city undermining continental community' is the wordplay.
'french city' becomes 'nice'.
'undermining' says to put letters next to each other.
'continental community' becomes 'eu'.
'nice' put after 'eu' is 'EUNICE'.
'from' is the link.
(Other definitions for eunice that I've seen before include "Female name deriving from happy victory in Greek" , "Girl's name" , "Woman" , "Girl" .)
