Subject has say in story (5)
I believe the answer is:
liege
'subject' is the definition.
(I've seen this before)
'say in story' is the wordplay.
'say' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'in' indicates putting letters inside.
'story' becomes 'lie' (story can mean a fabrication).
'eg' inserted inside 'lie' is 'LIEGE'.
'has' is the link.
(Other definitions for liege that I've seen before include "City in eastern Belgium" , "Belgian city or feudal chief" , "World War one battle site" , "Subject in history" , "Vassal, subject" .)
