King associated with gold (5)
I believe the answer is:
midas
'king associated with gold' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for midas that I've seen before include "Legendary king whose touch turned things to gold" , "One with a golden touch" , "King who turned what he touched to gold" , "I'm sad (anag) -- king of Phrygia" , "Everything he touched turned to gold" .)
