Get to the top on Tyneside? (7)
I believe the answer is:
scalene
'get to the top on tyneside?' is the definition.
I can't judge whether this defines the answer.
'get to the top on tyneside?' is the wordplay.
'get to the top' becomes 'scale'.
'on' is a charade indicator (letters next to each other).
'tyneside?' becomes 'ne' (region in North East of England).
'scale'+'ne'='SCALENE'
(Other definitions for scalene that I've seen before include "Having no sides for a match" , "(Of triangle) having three unequal sides" , "not having evenly matched sides" , "Neither equilateral nor isosceles" , "(Of triangle) with no sides equal" .)
