Support current attitude on stupid person (10)
I believe the answer is:
assistance
'support' is the definition.
(thesaurus)
'current attitude on stupid person' is the wordplay.
'current' becomes 'i' (symbol for electric current).
'attitude' becomes 'stance' (stance is a kind of attitude**).
'on' is a charade indicator (letters next to each other).
'stupid person' becomes 'ass' (I've seen this before).
'i'+'stance'='istance'
'istance' after 'ass' is 'ASSISTANCE'.
(Other definitions for assistance that I've seen before include "Support" , "Help" , "Aid" .)
