Soak doctor and nurse beside empty carwash (6)
I believe the answer is:
drench
'soak' is the definition.
(I know that soak can be written as drench)
'doctor and nurse beside empty carwash' is the wordplay.
'doctor' becomes 'dr' (abbreviation).
'and' is a charade indicator (letters next to each other).
'nurse' becomes 'EN' (abbreviation for enrolled nurse).
'beside' says to put letters next to each other (I've seen this in other clues).
'empty' says to hollow out the word (remove centre letters).
'carwash' with its middle taken out is 'ch'.
'dr'+'en'+'ch'='DRENCH'
(Other definitions for drench that I've seen before include "Swamp" , "Soak, souse" , "Soak, dowse" , "Wet thoroughly, soak" , "Soak with liquid" .)
