Quote or mention (4)
I believe the answer is:
cite
I believe this clue is a double definition.
'quote' is the first definition.
(I know that quote can be written as cite)
'mention' is the second definition.
(to cite is to mention or quote)
(Other definitions for cite that I've seen before include "Adduce as proof" , "Quote as evidence" , "Repeat a passage from some written work" , "Quote as an example or in support" , "Summon - quote" .)
