Superior pork pie brought round for one (5)
I believe the answer is:
liege
'superior' is the definition.
(feudal term for one's superior)
'pork pie brought round for one' is the wordplay.
'pork pie' becomes 'lie' ('pork pie' is Cockney rhyming slang for a lie).
'brought round' says the letters should be written backwards.
'for one' becomes 'eg' (both can mean 'for example').
'eg' reversed gives 'ge'.
'lie'+'ge'='LIEGE'
(Other definitions for liege that I've seen before include "Large Belgian city" , "Belgian city or feudal chief" , "Belgian city on Meuse" , "On about one East Belgium city" , "Faithful," .)
