Flooded, swamped (9)
I believe the answer is:
inundated
I believe this is a double definition.
'flooded' is the first definition.
(I know that flooded can be written as inundated)
'swamped' is the second definition.
('inundate' can be a synonym of 'swamp')
(Other definitions for inundated that I've seen before include "flooded" , "Deluged" , "drowned" .)
