Teenagers make fuss over the French perfumes (11)
I believe the answer is:
adolescents
'teenagers' is the definition.
('adolescent' can be a synonym of 'teenager')
'fuss over the french perfumes' is the wordplay.
'fuss' becomes 'ado' ('ado' can be a synonym of 'fuss'**).
'over' says to put letters next to each other.
'the french' becomes 'le'.
'perfumes' becomes 'scents' ('scent' can be a synonym of 'perfume').
'ado'+'le'+'scents'='ADOLESCENTS'
'make' acts as a link.
(Other definitions for adolescents that I've seen before include "Youths" , "Teenagers" , "Kids" , "Young people" .)
