Made reference to; mentioned (5)
I believe the answer is:
cited
I believe this clue is a double definition.
'made reference to' is the first definition.
(I've seen this in another clue)
'mentioned' is the second definition.
('cite' can be a synonym of 'mention')
(Other definitions for cited that I've seen before include "Called for" , "Summoned" , "Commended" , "Quoted or mentioned as example" , "Made reference to -- edict (anag)" .)
