Refer to some incitement (4)
I believe the answer is:
cite
'refer to' is the definition.
(synonyms)
'some incitement' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'CITE' is hidden within 'incitement'.
(Other definitions for cite that I've seen before include "Adduce as proof" , "Make reference to" , "Use quotations" , "Quote (an author)" , "Quote as an example or in support" .)
