Honourable post (7)
I believe the answer is:
upright
This clue is a double definition.
'honourable' is the first definition.
(I've seen this before)
'post' is the second definition.
(vertical post)
(Other definitions for upright that I've seen before include "Keyboard instrument" , "Perpendicular" , "deserving respect" , "Standing straight up" , "extremely reliable?" .)
