Native of Tyneside (7)
I believe the answer is:
geordie
'native of tyneside' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for geordie that I've seen before include "Inhabitant of Tyneside" , "Newcastle-upon-Tyne native" , "Tynesider" , "Northern chap" , "One from Newcastle" .)
