Excuses made by the Parisian to fine female carrying son (4,3)
I believe the answer is:
lets off
'excuses' is the definition.
('let off' can be a synonym of 'excuse')
'the parisian to fine female carrying son' is the wordplay.
'the parisian' becomes 'le' (definite article in French).
'fine' becomes 'f' (abbreviation).
'female' becomes 'f' (abbreviation).
'carrying' is an insertion indicator.
'son' becomes 's'.
'to'+'f'+'f'='toff'
'toff' going around 's' is 'tsoff'.
'le'+'tsoff'='LETS OFF'
'made by' is the link.
(Other definitions for lets off that I've seen before include "excuses" , "Pardons" .)
