Earl or duke, eg (8)
I believe the answer is:
nobleman
This clue is a double definition.
'earl' is the first definition.
(thesaurus)
'duke eg' is the second definition.
(duke is a kind of nobleman)
(Other definitions for nobleman that I've seen before include "Member of the aristocracy" , "count, perhaps" , "Earl, say" , "High-ranking male" , "I have a title" .)
