Girl turning Scottish not in position (7)
I believe the answer is:
eleanor
'girl' is the definition.
'turning scottish not in position' is the wordplay.
'turning' says the letters should be written in reverse.
'scottish not' becomes 'nae' (I've seen this in another clue).
'in' is an insertion indicator.
'position' becomes 'role' (I've seen this in another clue).
'nae' placed into 'role' is 'ronaele'.
'ronaele' back-to-front is 'ELEANOR'.
(Other definitions for eleanor that I've seen before include "-- Bron, actress" , "girl" , "Franklin D. Roosevelt's wife" , "A reel by Ringo (anag) -- Beatles song" , "Lady" .)
