Part of the goal is to be honest (7)
I believe the answer is:
upright
I believe this is a double definition.
'part of the goal' is the first definition.
('upright' is part of 'goal')
'honest' is the second definition.
(I've seen this before)
'is to be' acts as a link.
(Other definitions for upright that I've seen before include "beyond reproach" , "Key item" , "Type of piano" , "support" , "Sort of piano" .)
