Favour girl, teetotal and English (7)
I believe the answer is:
rosette
'favour' is the definition.
('favour' historically meant a token of affection)
'girl teetotal and english' is the wordplay.
'girl' becomes 'rose' (**).
'teetotal' becomes 'tt' (abbreviation).
'and' says to put letters next to each other.
'english' becomes 'e' (abbreviation).
'rose'+'tt'+'e'='ROSETTE'
(Other definitions for rosette that I've seen before include "sign of support for party" , "Decoration made of ribbons" , "Flower-like badge" , "Decorative ribbon" , "Ribbon decoration" .)
