Attorney and politician, a bit wet (4)
I believe the answer is:
damp
'a bit wet' is the definition.
(I've seen this before)
'attorney and politician' is the wordplay.
'attorney' becomes 'da' (District Attorney).
'and' means one lot of letters go next to another.
'politician' becomes 'mp'.
'da'+'mp'='DAMP'
(Other definitions for damp that I've seen before include "Unenthusiastic" , "Humid" , "Moist air" , "Somewhat moist" , "Rising -, TV sitcom" .)
