Appeal of the Parisian father’s embraced (4)
I believe the answer is:
plea
'appeal' is the definition.
(I know that plea is a type of appeal)
'the parisian father's embraced' is the wordplay.
'the parisian' becomes 'le' (definite article in French).
'father' becomes 'pa' (pa can mean dad or father).
'embraced' is an insertion indicator.
'le' put within 'pa' is 'PLEA'.
'of' is the link.
(Other definitions for plea that I've seen before include "Excuse, entreaty" , "Humble request for help" , "Excuse - pretext" , "Intercession" , "Answer made by the accused to the charge" .)
