Quoted (5)
'quoted' is the definition.
('cite' can be a synonym of 'quote')
This is all the clue.
(Other definitions for cited that I've seen before include "Quoted or mentioned as example" , "Summoned" , "Made reference to -- edict (anag)" , "Called for" , "Commended" .)
(Other definitions for oft that I've seen before include "Frequently, as the poet would have it" , "Old song'... in the stilly night'" , "Frequently, in verse" , "Many times, to the poet" , "Many times (archaic)" .)
