Attorney finds politician wet (4)
I believe the answer is:
damp
'wet' is the definition.
(similar in meaning)
'attorney finds politician' is the wordplay.
'attorney' becomes 'DA' (abbreviation for District Attorney).
'finds' is a charade indicator (letters next to each other).
'politician' becomes 'MP' (Member of Parliament).
'da'+'mp'='DAMP'
(Other definitions for damp that I've seen before include "Clammy" , "(Slightly) wet" , "Moist air" , "Moisture" , "Somewhat moist" .)
