Flood in a Parisian court (8)
I believe the answer is:
inundate
'flood' is the definition.
(I know that flood can be written as inundate)
'in a parisian court' is the wordplay.
'a parisian' becomes 'un' ('a' in French).
'court' becomes 'date' (romantically pursue).
'in'+'un'+'date'='INUNDATE'
(Other definitions for inundate that I've seen before include "Flood - and unite (anag)" , "Flood, overwhelm" , "Submerge or cover in water" , "Overwhelm with things to be done" , "Flood, cover with water" .)
