Attorney getting politician slightly wet (4)
I believe the answer is:
damp
'slightly wet' is the definition.
(I've seen this before)
'attorney getting politician' is the wordplay.
'attorney' becomes 'da' (District Attorney).
'getting' 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 "(Slightly) wet" , "Somewhat moist" , "Humid" , "Slightly moist" , "Rising -, TV sitcom" .)
