Daughter given violent shock with wife leaving? Completely swamped (8)
I believe the answer is:
drenched
'swamped' is the definition.
('drench' can be a synonym of 'swamp')
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for drenched that I've seen before include "forcibly administered medicine" , "Soaking, sopping wet" , "Thoroughly soaked" , "Soaked by rain" .)
