I believe the answer is:

adduce

'cite' is the definition.
(synonyms)

I don't understand how the remainder of the clue works.

(Other definitions for adduce that I've seen before include "Agreement, harmony" , "Cite as example or proof" , "Advance evidence for" , "Allege" , "Cue dad (anag)" .)

I've seen this clue in The Guardian.
