Reputation for being upright (8)
I believe the answer is:
standing
This clue is a double definition.
'reputation' is the first definition.
(one's standing is one's reputation or status)
'being upright' is the second definition.
('stand' can be a synonym of 'be upright')
'for' acts as a link.
(Other definitions for standing that I've seen before include "Upright" , "Being a candidate - status" , "Status, reputation" , "Still in" , "Social or financial status" .)
