Principled noble (7)
I believe the answer is:
upright
This clue is a double definition.
'principled' is the first definition.
(thesaurus)
'noble' is the second definition.
(I've seen this before)
(Other definitions for upright that I've seen before include "Pole; principled" , "Perpendicular" , "Vertical post in rugby goal - strictly honourable" , "Sort of piano" , "Erect - honest" .)
