Heir has triumph with gold (9)
I believe the answer is:
successor
'heir' is the definition.
(I know that heir can be written as successor)
'triumph with gold' is the wordplay.
'triumph' becomes 'success' (I've seen this before).
'with' says to put letters next to each other.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'success'+'or'='SUCCESSOR'
'has' is the link.
(Other definitions for successor that I've seen before include "Heir" , "for one of the following people" , "I follow" , "Person who follows next in order" , "One who's after" .)
