Excuse made by the Parisian to fine female (3,3)
I believe the answer is:
let off
'excuse' is the definition.
('let off' can be a synonym of 'excuse')
'the parisian to fine female' is the wordplay.
'the parisian' becomes 'le' (definite article in French).
'fine' becomes 'f' (abbreviation).
'female' becomes 'f' (abbreviation).
'le'+'to'+'f'+'f'='LET OFF'
'made by' acts as a link.
(Other definitions for let off that I've seen before include "Set free without charge" , "Go easy on" , "Discharge - absolve" , "Chance to escape defeat" , "Detonate" .)
