Flood in a French court (8)
I believe the answer is:
inundate
'flood' is the definition.
('inundate' can be a synonym of 'flood')
'in a french court' is the wordplay.
'a french' becomes 'un' ('a' in French).
'court' becomes 'date' (romantically pursue).
'in'+'un'+'date'='INUNDATE'
(Other definitions for inundate that I've seen before include "be overwhelming" , "Overrun" , "Overwhelm, swamp" , "Submerge or cover in water" , "Flood - and unite (anag)" .)
