Overwhelm in a Parisian court (8)
I believe the answer is:
inundate
'overwhelm' is the definition.
(thesaurus)
'in a parisian court' is the wordplay.
'a parisian' becomes 'un'.
'court' becomes 'date' (romantically pursue).
'in'+'un'+'date'='INUNDATE'
(Other definitions for inundate that I've seen before include "be overwhelming" , "Flood, overwhelm" , "Overwhelm (as if) with water" , "Overwhelm, swamp" , "Flood (a place)" .)
