Incite a punt (4)
I believe the answer is:
abet
'incite' is the definition.
(thesaurus)
'a punt' is the wordplay.
'punt' becomes 'bet' (I've seen this in other clues).
'a'+'bet'='ABET'
(Other definitions for abet that I've seen before include "Aid and help, perhaps in crime" , "Urge on, help" , "Assist (in doing wrong?)" , "Assist in some nefarious activity" , "Help to do something wrong" .)
