Prophet almost died, drenched in water (5)
I believe the answer is:
hosed
'drenched in water' is the definition.
(drenched with a hose)
'prophet almost died' is the wordplay.
'prophet' becomes 'Hosea' (Old Testament figure).
'almost' means to remove the last letter (most of the word but not all of it).
'died' becomes 'd' (abbreviation next to the year of someone's death).
'hosea' with its last letter removed is 'hose'.
'hose'+'d'='HOSED'
(Other definitions for hosed that I've seen before include "wearing tights?" , "washed" , "Watered with a flexible pipe" , "swilled down with water" .)
