Ego, dire, corrected in northerner (7)
I believe the answer is:
geordie
'northerner' is the definition.
(term for a person from Tyneside in NE England)
'ego dire corrected' is the wordplay.
'corrected' indicates anagramming the letters.
'ego'+'dire'='egodire'
'egodire' anagrammed gives 'GEORDIE'.
'in' acts as a link.
(Other definitions for geordie that I've seen before include "Newcastle-upon-Tyne native" , "Newcastle-born?" , "Tynesider" , "Newcastle person" , "One from Newcastle" .)
